I’ve been trying to run a 32 bit app on my 128 GB MacBook Air and it’s been a huge PITA. Xcode requires you to be on the latest version which means that I had to upgrade after uninstalling many apps and cleaning up. It requires something like 30 GB free to get to Big Sur. Then I finally get to trying to download Mojave to install but the App Store doesn’t allow a download when you’re in a newer version - so I have to go to another site that specializes in this type of thing- and then make a VM for Mojave on a machine with no memory so I have to move your things to an external hard drive. I still haven’t finished the install to be able to run one 32 bit app I wanted to dig into. Any suggestions would be welcome.

You can download older versions of Xcode via https://developer.apple.com/downloads https://developer.apple.com/downloads — if you don’t care about shipping anything to an Apple walled garden but just want to dig into some old software, definitely stay on an older version of OS X and grab an older copy of Xcode. EDIT: additionally, I’d recommend going for a version of Xcode as close to the version used for developing the software you’re interested in as possible — balancing out what version of Mac OS (you have / are targeting / most up to date) is compatible with the versions of Xcode close to it. Some major Xcode updates will break compilation and you’ll have to fix minor issues to move forward, which could be brutal in a larger codebase.

  I have VM's of different major OS X releases and corresponding versions of xCode. It's super valuable for getting stuff on Github from different eras to actually compile.

If the thing you are trying to run has/had a Windows counterpart you could try using crossover which can run 32 bit Windows apps on Mac.

  I just tried this and got "Install failed with error: Update not found". A few days back I was searching around for how to download old macOS/OS X versions, so that I could run a VM to test my app [0]. For the first hour or so, all I could find was sites that linked to the official App Store downloads for the last 3 OSes, which didn't work. The page would open in the App Store app, I'd click "Get", and it would say that it wasn't found. This command unfortunately did the same, which makes me wonder if this is something to do with my Apple account, or maybe that they've taken down those downloads? What ended up working for me was dosdude's patchers: 10.12 Sierra: http://dosdude1.com/sierrapatch.html http://dosdude1.com/sierrapatch.html 10.13 High Sierra: http://dosdude1.com/highsierra/ http://dosdude1.com/highsierra/ 10.14 Mojave: http://dosdude1.com/mojave/ http://dosdude1.com/mojave/ 10.15 Catalina: http://dosdude1.com/catalina/ http://dosdude1.com/catalina/ These tools are meant for patching old OS X versions to run on unsupported Macs, but that wasn't the feature I needed. The important thing for me was their "Download" button, which downloads the installer directly from Apple's servers. It was a huge relief and I was finally able to test my app properly on older (virtualized) OSes using Parallels [1], which was even having a sale at the time (maybe still?). 0: my app is Recut, an automated video editor - https://getrecut.com https://getrecut.com - which supports back to 10.13 High Sierra 1: https://www.parallels.com/ https://www.parallels.com/

    You can find the direct download links manually by looking for the package in the sucatalog for the OS version of interest: https://gist.github.com/meyer/b14c87d162366f0428a99cd2ff0d0b8b https://gist.github.com/meyer/b14c87d162366f0428a99cd2ff0d0b... There's also this interestingly named tool which essentially automates the process: https://github.com/corpnewt/gibMacOS https://github.com/corpnewt/gibMacOS
