if you work on a company mac and don't have install privileges.

I’ve found installing apps to ~/Applications to be a way around this. It doesn’t require the admin rights that installing to /Applications does.

The app is only installed for the user, instead of all users, but that’s not an issue for a single user system. I haven’t run into any issues so far.

Even for app I can install to /Applications at work (via self service from IT), I opt to install many of them to ~/Applications anyway, as it allows the auto-updater to run without having to jump through hoops.

Your mileage may vary, if your company know about this and takes extra steps to lock things down beyond restricting admin rights.
