my Mac book won’t boot past the apple logo. I get a panic (cpu 0 caller 0xffffff8000ef0354) message. The last thing I did with it was start it as a head drive holding the T button while powering on and connecting to my iMac to transfer files. I’ve done this before without problems. Now it won’t boot?
Hi,
It seems you deleted some of important kernel extension/s.
Try to boot in Recovery mode then run DiskUtility and FirstAid to check your boot drive.
Use macOS Recovery on an Intel-based Mac - Apple Support
Use macOS Recovery on a Mac with Apple silicon - Apple Support
If it doesn't help, you need to reinstall macOS from Recovery mode.

I was able to boot in recovery mode and run disk utility to repair the hard drive the resulting message was that there wasn’t a problem with the hard drive. I still couldn’t get it to boot up through. Looks like I may need to reinstall Mac OS. I don’t know how I deleted the kernel extensions?
You were right. I had to do a reinstall of Mac OS. Working fine again now. Thanks for your help.
Mac book pro will not boot.
