Old programmers never die … they just use VM software.
I use Parallels 16 on Catalina. If you buy parallels, waut till cyber week in the US, you might get a little money savings. also, make sure DO NOT BUY the subscrption version, get the download licence version… then you don't have to pay for updates you won't use..
I’m running the following VM’s on my Catalina Mac Book Pro
- win 2000. (yes.. I still run it and use it to test things - even though it is 20 or so years old)
- win xp
- win 2008 server
- Win 2012 server
- Win 2016 server
- win 2019 servers
- win 10 (older and newer releases)
- Mac OS 10.6.8 (snow leopard)
- El Capitan
- High Sierra
- Mojave (so that I can still run studio 5 if need be)
- Big Sur
- Ubuntu linux
you have to be using an Intel based max to get all those.
and you can run the virtual machines in two modes. One is normal mode, where it looks like you are running a windows VM in its own windowl, or coherence mode… which makes the windows MDI interface go away and you just see ‘windows’ windows within your mac environment. its rather clever — so whiel the indow looks like another operating system, it is no longer in a container. Kind of seamless.
Making the older operating systems took time …. so I kept some images of them as backup.
