This is a cautionary tale. 2019 iMac, i9, Mojave 10.14. Running Logic Pro X. Attempted to install USB audio interface, which had been working well on previous iMac. Downloaded latest version of driver and restart to install. Boot up bar would display, but only advance 60% or so and stop. Restarting multiple times had same result. Mac would not boot up whatsoever. Subsequently found short note on website of interface manufacturer stating “a small number of reports” of this behavior had been reported, and they are addressing that with Apple. I don’t know what a “small number “ is, but if you’re included in that, it may as well be 100%. So my one week old iMac was effectively dead. Called AppleCare. Many efforts to boot into recovery mode, as instructed, failed. Also no success booting into safe mode. AppleCare rep was then making arrangements for me to bring the Mac back to the Apple Store. Not an easy thing for me to do. Half an hour later, I decided to call back AppleCare. A different tech had me repeatedly try to boot into recovery mode again. After many attempts with same failure to boot up, it suddenly did. I was then able to access TimeMachine on an external disc while in recovery mode, and restore the Mac to the previous date. Thankfully, all is well with the Mac now. But I have no means of recording audio. I am searching and considering options for new interface, but communicating with tech support for each of these requesting some assurance of compatibility before I buy anything.
