I recently had to retire a very ancient Mac computer running Mac OS 10.13 on which I was able to type in IPA using SIL keyboard drivers and SIL fonts or any Unicode font. Now on the new machine, I'm running Mac OS 15 and the SIL keyboard drivers don't work. I have also installed the Keyman utility along with two IPA keyboards, and those also don't work.

If I can't type in IPA, I'm really in trouble. SIL have provided no advice that worked, and I was wondering if anyone knows how to fix the problem. Thank you.
