Expect macOS Mojave 10.14 support to end in late 2021. With Apple's release of macOS Big Sur 11, macOS Mojave 10.14 will become the third oldest version and will cease to be supported at that time. As a result, IT Field Services will stop providing software support for all Mac computers running macOS Mojave 10.14 in late 2021. Color effects manager for Razer devices for macOS. Supports High Sierra (10.13) to Big Sur (11.0). Made by the community, based on openrazer. 1kc/razer-macos.
It's quite possible your computer is too old to upgrade past Lion, but if you can then El Capitan will probably be your limit.
I was able to download the macOS High Sierra 10.13.6 full installer version thanks to a mid 2012 macbook pro with macOS El Capitan installed. All other attempts with the latest mac book pro and already installed versions of the operating system (Catalina or Mojave) have been unsuccessful.
Upgrading to El Capitan
You can upgrade to El Capitan from Lion or directly from Snow Leopard. El Capitan can be downloaded from the Mac App Store for FREE.
To upgrade to El Capitan you must have Snow Leopard 10.6.8 or Lion installed. Download El Capitan from the App Store. Sign in using your Apple ID. El Capitan is free. The file is quite large, over 5 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
Macs that can be upgraded to OS X El Capitan
1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities' folder. It's displayed in the panel on the right.
Are my applications compatible? See App Compatibility Table - RoaringApps.
Upgrading to Lion
If your computer does not meet the requirements to install El Capitan, it may still meet the requirements to install Lion.
You can purchase Lion at the Online Apple Store. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
