Is it possible to download and install multiple versions of Safari on macOS? I need to test something out on my MacBook with the latest version of Safari (13), but I don't want to update my current Safari browser to the latest version. I want to be able to keep my current older version of Safari UNTOUCHED and the newest version of Safari both installed and usable on my Mac computer. Is this possible?

  • Not very easily. Virtual machine seems to be a way. I don't know if you can keep multiple partitions for multiple os versions. – anki Mar 31 '20 at 7:12
  • someone else told me I would just need to rename my old version as Legacy Safari or something like that and that I should still be able to run both – Arlen Mar 31 '20 at 7:28
  • is virtual box the best free VM? – Arlen Mar 31 '20 at 7:30
  • I have no idea how to use a VM, can you help me out? – Arlen Apr 3 '20 at 12:41
  • you can try Parallels with its 15 days trial. If it works well, VirtualBox is free, just looks weird. I haven't tried vmware – anki Apr 3 '20 at 12:54

Updates to Safari tend to include updates to the WebKit system framework on which Safari relies. (The WebKit framework is separate from the app, and is then available to other apps.)

Executing an app that was built for a different framework from the last one you installed is likely to cause problems.

  • Someone on another site told me I should use Safari Technology Preview app. Is that a good idea? – Arlen Mar 31 '20 at 20:13
  • Safari Preview is like a beta. It's an advance look at new technologies. It will have benefits and disadvantages. – benwiggy Mar 31 '20 at 21:44
  • Can I use Safari Preview for an older version of Safari such as Safari version 11.12? – Arlen Mar 31 '20 at 22:20
  • Do you have an external hard drive? you might download latest version of Safari onto an external hard drive. – Natsfan Mar 31 '20 at 22:26
  • No, I do not. At least no drive that is empty. All the drives I have have data on them. – Arlen Mar 31 '20 at 22:30

No, it is probably not possible because Safari is a part of macOS. New versions of Safari come with macOS but you can try finding the Safari downloads at https://support.apple.com/downloads. Double click the .dmg file and complete the installation.

  • I've never heard of it but I wouldn't recommend it if it is third party. If you really do need different versions, you can try using a macOS Virtual Machine. If you want a macOS VM, you will need the ISO. – user368931 Apr 1 '20 at 21:45
  • It's this: developer.apple.com/safari/technology-preview – Arlen Apr 1 '20 at 21:55
  • Seems legit, you should try it. – user368931 Apr 1 '20 at 22:14
  • The only problem is it's only for the current version of Safari 13, not Safari 11. And if there are previews for Safari 11.1.2, I don't know where to find them. – Arlen Apr 1 '20 at 22:32
