Xcode is the Mac app that developers use to create apps for Apple’s platforms, like iOS. In this tutorial, you’ll learn how you can download and install Xcode on your Mac.

Here’s what we’ll get into:

After you start your Mac and before opening any apps you can move Xcode to another folder (with holding down the command key and dragging) and then moving it back to the Applications folder. It somehow bypasses the verification and your Mac is going to be working as usual with SIP until a restart.
Many Catalina directories are not writable by the old tool installer. XProtect prevents modification. The newest Xcode installer puts stuff in other places (not /System). Old tools may require using old OS volumes. – hotpaw2 Feb 18 '20 at 16:49.

3 approaches to download and install Xcode on your Mac
Tips and tricks to keep your Xcode up-to-date
How to install Xcode betas on your Mac

For me, the Xcode being verified 'forever' and slowing my computer to a crawl started after the first Catalina update. My computer was running full speed with the original Catalina install. Sending Xcode to Trash restores snappiness and speed.

Ready? Let’s go.

Xcode can only be installed on a Mac. Want to build apps with a PC? Check out your alternatives here.

How To Download Xcode for macOS

How do you download Xcode for macOS? You’ve got a few options:

Get Xcode via the Mac App Store
Download Xcode via developer.apple.com/downloads
Install through Mac App Store CLI (see below)

Let’s walk through the approaches you can use to download and install Xcode on your Mac, and their advantages. We’ll start with the Mac App Store, because that’s the simplest option.

Here’s how you can download and install via the Mac App Store:

Make sure you’re logged into macOS with your Apple ID
Open the Mac App Store app
Search for “xcode” in the search field, at the top-left
Click on the Xcode app item that appears
Click on the Get or Install buttom at the top-right to download and install Xcode

There are a few things you should know, though. Xcode is a huge app, about 7 gigabyte (GB) in size. You’ll need about 15 GB of free space on your Mac to install Xcode this way.

Installing via the App Store is simple, easy and seamless. Unfortunately, issues with downloading, like a lost connection, etc., usually means you’ll have to reattempt the download.

Author’s Note: Installing Xcode via the App Store never maxes out my download speed — not even close. On a 500 Mbps fiber line, it regularly drops down to 200 KB/s.

Installing Xcode on Mac

Installing Xcode via the Mac App Store is as simple as clicking Install. However, there’s an approach that gives you more control: developer.apple.com/download.

Here’s how that works:

Go to developer.apple.com/download and log in with your Apple ID
Click on More in the top-right of the page, next to Beta and Release
In the search field on the left, type “xcode” and press Enter
Locate and click the appropriate version of Xcode in the list
In the panel slides out, click the .xip filename, i.e. Xcode 12.xip and save/download that file onto your Mac

This will download a .xip file, which includes Xcode. The download size is currently about 7 gigabyte (GB). You’ll need at least twice that size of free storage on your Mac to install Xcode with this approach. Downloading Xcode this way is often faster than through the Mac App Store.

Once you’ve downloaded Xcode, open and unzip the .xip file. This may take a while. You can then drag-and-drop the Xcode.app file to your ~/Applications folder. Finally, start the Xcode app. You’ll be greeted with the following prompt:

Click Install in this prompt. Xcode will now attempt to install the Xcode Command Line Tools on your Mac. They are CLI tools used to compile apps with Xcode, among other things. You often need these tools to work with other programming languages on Mac, as well.

A disadvantage of manually installing Xcode through the Developer portal is that Xcode won’t automatically update. This isn’t necessarily a bad thing, however, because you can use this approach to install multiple versions of Xcode side-by-side. This is helpful for debugging or trying out beta versions of Xcode (see below).

Xcode Mac Catalina

There’s another, more hidden benefit. Installing Xcode through the Mac App Store limits you to the most recent version of Xcode. If your version of macOS or Mac OS X doesn’t support the latest version of Xcode, you can usually install older versions via developer.apple.com!

You can pinpoint the latest version of Xcode that your Mac supports by cross-referencing a few tables on Wikipedia. First, figure out what macOS version you have. Then, go to the Xcode wiki, and find your version of macOS in the min macOS version to run column between Xcode 9.x and 12.x. The version of Xcode you can run is in the row above the one you found. For example, the latest version of Xcode you can run on macOS 10.13.6 (High Sierra) is Xcode 10.1. Keep in mind that running an older version of Xcode often limits for which iOS, Swift and SwiftUI versions you can build.

Updating Xcode to The Latest Version

How do you keep your Xcode up-to-date? Apple regularly releases new versions of Xcode. They typically include bug fixes and performance improvements, as well as new Xcode features, like the minimap.

More importantly, new Xcode versions include new versions of the iOS SDKs, Swift and SwiftUI. You can only use these new technologies with the latest versions of Xcode.

You can update your Xcode to the latest versions like this:

If you’ve installed Xcode via the App Store, updates happen automatically, or you can manually initiate an update in the Updates tab of the app
If you’ve manually installed Xcode via developer.apple.com, you’ll also need to manually install the newer version; updates aren’t automatic

How do you know if Xcode has a new version?

You get a notification on your Mac (if installed via App Store)
Keep an eye on developer.apple.com/news/releases (official)
Check out xcodereleases.com
Follow @XcodeReleases on Twitter

By the way, there’s a 3rd way to download and install Xcode on your Mac. It’s called mas-cli, and it’s essentially a Command Line Interface (CLI) wrapper for the Mac App Store. It uses the App Store – from the command line… Nice!

You can install mas-cli via Homebrew, a package manager for Mac. Installing mas-cli via Homebrew happens like this:

You can then list apps installed through the App Store on your Mac, with:

You can then search for Xcode like this:

Then, copy the numerical code you see on screen to install Xcode:

You can find outdated apps with mas outdated. You can then upgrade all outdated apps with mas upgrade, or selectively update Xcode by its identifier:

Awesome!

Author’s Note: As I understand it, you’ll need to have installed an app via the App Store before you can install it again with mas-cli.

Getting Xcode Beta Versions

Apple regularly releases beta versions of upcoming software, like iOS, macOS and Xcode. This enables developers to try out new features before they become available to the general public, and provide feedback and bug reports back to Apple.

How can you download and install Xcode’s beta versions? Here’s how:

Go to developer.apple.com/download and log in with your Apple ID
Choose one of the following:
- Click Beta in the top-right:
  1. Select Applications
  2. Locate the featured Xcode beta you need
  3. Click Download
- Click More in the top-right
  1. Use the search field to find “xcode”
  2. Locate the Xcode beta you need
  3. Expand the panel by clicking on it
  4. Click the .xip to download
Once you’ve got a .xip, unzip it, copy the .app to your ~/Applications folder, and start the Xcode app.

As we’ve discussed before, you can install multiple versions of Xcode side-by-side with this approach. You can, for example, have the regular Xcode installed via the App Store, and install a beta version of Xcode next to it.

You don’t need to have a paid Developer Account to install betas of Xcode. Just use the free Apple Developer Account. It can occasionally happen that Apple restricts beta software to paid subscribers only, however.

If you’re installing multiple Xcodes, change their filenames to reflect their versions. That makes it easier to tell them apart! Just so you know: when you switch between installed Xcode versions, you usually get that “Install additional components” prompt again. There are ways around that, but it’s simplest to just let it install again whenever Xcode needs to.

Mac OS is Apple's operating system for their Apple iMac range of computers. It uses a combination of technologies including Mach, NetBSD, FreeBSD, NeXT, and Cocoa.
The current Apple iMac range now use Intel hardware and processors. macOS Mojave the latest version of Mac OS using version number 10.15.

2. What differences are there with Catalina (10.15) and previous versions?

Like the last 5 versions of Mac OS, it is now completely Intel native and supports some new technology as well.

Runs Intel 64 bit applications only.
Dashboard removed. iTunes replaced with TV, Music, Podcasts.
Sidecar to use iPad as second display or mirror your mac desktop.
Screen time to monitor usage, schedule download, set limits for apps etc.
Find My app replaces Find my iPhone and Find my Friends apps.
Voice control to interact with your mac.
Photos to showcase your best or important photos.
Plus many other changes.
MacOS Catalina is available to download from the AppStore from Autumn (Fall) 2019.

3. What are the minimum requirements to run Catalina on my iMac?

You need a Apple iMac that has a 64 bit Intel i3, i5, i7 or Xeon processor, manufactured from late 2012 onwards and supports 64 bit EFI and Metal.
For memory, you need at least 2 GB of RAM (4GB recommended). For hard disk space, you need at least 8.8 GB of free space to install Sierra.
For additional requirements, see Apple's Technical Specs.

MacBook (Early 2015 or newer)
MacBook Air (Mid 2012 or newer)
MacBook Pro (Mid 2012 or newer)
Mac mini (Late 2012 or newer)
iMac (Late 2012 or newer)
iMac Pro (2017)
Mac Pro (Late 2013 or newer)

4. How do I create a bootable USB disk with Catalina?

You can no longer create a bootable DVD but you can create a bootable USB stick. You can create it from the disk image from the Install macOS installation file you downloaded:

a) Locate the Mac OS X Catalina installation file in the Applications folder. If it is not there, download it again from the App Store.
b) Open the Terminal program and start a shell,
c) Insert a blank USB disc in your Mac.
d) Enter the following command in the Terminal window shell. Replace untitled with the name of your USB Stick:

5. How do I install Catalina?

a) Open the AppStore icon in the dock.
b) Click on Sign In link in the Quick Links.
c) Click on macOS Catalina icon to purchase (it is free) and download the program (previous versions are available under Purchases).
d) The program may take an hour or so to download (approx 4 GB).
e) Open the Applications folder and you will find the Install macOS Catalina icon.
f) I would recommend backing up this file to an external disk if you want to use it again later and prevent having to download it again.
g) Run Install macOS Catalina to begin installation and follow the prompts.
h) If you have a free second partition, setup using DiskUtil, you can install Catalina on a 2nd disk and leave your current OS alone.

6. How do I use the Recovery feature?

When you boot up, press the Command-R key combination to enter HD Recovery mode. You can then select one of the following options: Restore from Time Machine Backup, Reinstall Mac OS X, Get Help Online (using Safari browser) or load the Disk Utility.

a) Time Machine Backup. This allows you restore an entire backup of your Mac OS X installation, applications and files back to a hard disk partition of your choice.
b) The Reinstall Mac OS X will reinstall Mac OS X but it doesn't include all the files to restore, so it will need network access to download the necessary files from the AppStore.
c) Get Help Online will open Safari so that you have access to the Internet to access instructions and other information to allow you to restore your Mac.
d) Disk Utility will open the disk tool to partition or repair your hard disk.

7. What applications can I run on macOS Catalina?

Mac OS can run Intel 64 bit applications. Most of the 64 bit apps for Mac OS X Sierra or later should be able to run on Catalina.
32-bit applications, components or plug-ins will no longer run. 32 bit programs will show a No Entry sign on the program icon.

Applications included with Catalina: Books, Calculator, Calendar, Chess, Contacts, Dictionary, DVD Player, Facetime, Font Book, iBooks, Image Capture,
Launchpad, Mail, Maps, Messages, Mission Control, Music, News, Notes, Photo Booth, Photos, Podcasts, Preview, Quicktime Player, Reminders, Safari, Siri, Stickies, System Preferences, Stickies, Time Machine, TV, Voice Memos and Utilities.

For example:
a) Office Applications. For Microsoft Office, you need at least Office 365, 2016 or 2019. You can also use iWork, Open Office, Libre Office and Neo Office 2017.
b) Apple Garageband, iMovie, and Photos are available from the App Store.
c) Adobe Creative Suite. Use the latest Creative Cloud 2019.
d) Media Players. As well as iTunes and Quicktime, you can download new versions of players such as VLC Player, Real Player and Switch (for WMP files).
e) Accounting. Latest Quicken should work on Mac OS and Home/Business Accountz.
f) DTP. See Scribus, Adobe CC InDesign, and for Quark XPress you need version 2019 or later.
g) Graphics. See Adobe CS 2019 for Photoshop, Photoshop Elements 2019 or Gimp.
h) Games. See games on the App Store or from Steam Powered and Mac Games World.
i) Database. See Tap Forms 5 or File Maker.
j) Visualization. See Parallels Desktop, VMWare Fusion, VirtualBox or CrossOver.
k) Development. See XCode, Unity 3D, Python, Java and many others.

A complete list of tested applications can be found on RoaringApps.

NB: This list will be updated as and when apps are tested as compatible.

8. How to I accessed shared resources on Windows systems from my Mac?

Windows computers uses a protocol called SMB (Simple Message Block) and CIFS (Common Internet Filing System) to share resources such a files and folders. On a Windows computer, this uses the Microsoft Client for Networks. Shares can be accessing using the format computernamesharename.

Apple Macs can also use SMB/CIFS. To access a Windows share, select CMD+K (to select Go to Server) and enter smb://servername/sharename (you can use an IP address instead of a servername). If you forget the smb: part, it will use the default AFP (Apple Filing Protocol) which will only work on shared Mac resources.

To configure SMB or CIFS, make sure you have configured the Computer Name (hostname) correctly on the Mac (preferably with no spaces) in the Sharing control panel and enable Windows Sharing or File Sharing. In Options, enable Shares file and folders using SMB (Windows). You will also need to create and enable Accounts and set up Read/Write permissions to allow access to shared folders.

To configure membership of a Workgroup and set up a short NetBIOS name, you can do this in the Networks control panel. Select the adapter (e.g. Ethernet), click on Advanced and select the WINS tab to configure a NetBios Name and Workgroup. Not setting the workgroup name, can prevent access to SMB shares or logging in over the network.

SMBX in Mac OS X supports SMB1 and SMB2 but not the old NT Domain Controller features (most people will not use these features any way). Apple has replaced SMB with SMBX due to issues with the GPLv3 licensing requirements.

Use the terminal command 'smbd' to view logs when using smb client.

9. How do I secure may Mac from hackers, viruses and other threats?

You can do several things, including enabling the Firewall in the Security control panel. Make sure that Software Updates are regularly checked and applied and install some security software to check against viruses and malware:
a) McAfee LiveSafe or All Access for Mac which includes SiteAdvisor, a Firewall and anti-virus products.
b) VirusBarrier and Internet Security Barrier products from Intego.
c) The new ClamXav 3 anti-virus scanner.
d) Norton Security from Symantec.
e) Kaspersky Total Security Multi-Device.
f) F-Secure Safe for the Mac.
g) Use Gatekeeper, and restrict app download from just the App Store or from trusted identified developers.

NB: This list will be updated as and when apps are tested as compatible.

10. How do I check that my NAS backup device is compatible?

NAS (Network Attached Storage) devices are very useful for storing large amounts of data and for backups. OS X Lion has changed the protocols for AFP Netatalk to 2.2 which may break older NAS devices. To ensure that you can connect to your NAS with Lion, please update the firmware and software for your NAS devices. There are also updates for the AFP DHX2 Authentication for Synergy DiskStation Manager , QNAP and DROBO products. Use CIFS protocol instead of SMB for faster file access.
