ROBLOX puts great effort into developing unified code that runs across multiple platforms — PC, Mac and soon iPad — on a wide variety of hardware and software configurations. This summer, as we ratcheted up development efforts for ROBLOX on mobile devices and tablets, we found the software we use to compile our code was only compatible with either Mac OS X 10.5 (Leopard) or mobile devices. We were faced with a tough decision: maintain a separate code base for OS X 10.5 or discontinue support for it.

Common Macbook Air Problems and Solutions. Here are some common MacBook Air problems and their solutions that we are going to talk about in this article. But before we move on to discuss some of the most common MacBook Air problems and how to fix them, we must first know a thing or about the Apple-produced laptop itself.

In the interest of unified code, fast updates and future expansion to more platforms, we have opted to discontinue support for OS X 10.5. The change will take effect in the next two weeks.

OS X 10.5 users will still be able to browse Roblox.com and participate in all web-based features. Our analytics show less than 1% of ROBLOX players use OS X 10.5. If this change affects you and you’d like to continue playing and building games, we recommend you update your Mac’s operating system to at least OS X 10.6.

We want to make sure all ROBLOX users on OS X 10.5 have the option of continuing to play and build. We’ve contacted Apple, and the easiest update path is to call and purchase the latest operating system update on physical media. They will also be able to tell you whether your system can handle a more recent version of OS X.

Q. Why is ROBLOX discontinuing support for Mac OS X 10.5?

A. We would have to maintain a separate code base for Mac OS X 10.5 because the software we use to compile code for OS X 10.5 is not compatible with that of mobile devices. At this time, we are prioritizing a unified code base and development of ROBLOX for mobile devices.

It’s worth noting that Apple no longer supports OS X 10.5, nor do many common desktop applications, like Chrome and Firefox.

Q: I have a Mac. How can I tell if I’m running Mac OS X 10.5?

A: Go to the Apple Menu, then click About this Mac. If it says less than “Version 10.6”, you will need to upgrade to keep playing and building in ROBLOX.

Q. How can I update my Mac to keep playing ROBLOX?

A. You can call Apple direct at 1 800 MY APPLE to purchase an OS X update, delivered via physical media. They will tell you whether your system can handle the latest Mac operating system, OS X 10.8 Mountain Lion.

Q. Can I still browse Roblox.com on Mac OS X 10.5?

A. Yes. You can continue to browse the website and participate in all our social and economy features.

Q. Who should I contact with questions?

A. If you have any problems to report, please email info@roblox.com.

To get the latest features and maintain the security, stability, compatibility, and performance of your Mac, it's important to keep your software up to date. Apple recommends that you always use the latest macOS that is compatible with your Mac.

Learn how to upgrade to macOS Big Sur, the latest version of macOS.

Check compatibility

If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that your Mac doesn't have enough free storage space for the installation, or that the installer is too old to be opened on this version of macOS.

If you want to check compatibility before downloading the installer, learn about the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan, or Yosemite. You can also check compatible operating systems on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini, or Mac Pro.

Make a backup

Before installing, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Learn how to back up your Mac.

Download macOS

It takes time to download and install macOS, so make sure that you're plugged into AC power and have a reliable internet connection.

These installers from the App Store open automatically after you download them:

• macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks
• macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion
• macOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion, Lion

Your web browser downloads the following older installers as a disk image named InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It installs an app named Install [Version Name]. Open that app from your Applications folder to begin installing the operating system.

• macOS Sierra 10.12 can upgrade El Capitan, Yosemite, Mavericks, Mountain Lion, or Lion
• OS X El Capitan 10.11 can upgrade Yosemite, Mavericks, Mountain Lion, Lion, or Snow Leopard
• OS X Yosemite 10.10can upgrade Mavericks, Mountain Lion, Lion, or Snow Leopard

Install macOS

Follow the onscreen instructions in the installer. It might be easiest to begin installation in the evening so that it can complete overnight, if needed.

If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.

Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.

You might also be able to use macOS Recovery to reinstall the macOS you're using now, upgrade to the latest compatible macOS, or install the macOS that came with your Mac.
