Updating of macOS 11.5.x corrupts FPC on M1 Mac
lazarus / 33-macOS - Mac OS X

Since macOS 11.5 every new update (11.5.1, 11.5.2) damages FPC 3.2.2
binaries or configuration on M1-powered Mac.

Symptoms:

FPC refuses to cross-compile for x86_64/darwin.
Compilation for aarch64/darwin works fine.

Native aarch64/darwin compiler works fine:

Solution:

I found a simple workaround. Reinstallation of
fpc-3.2.2.intelarm64-macosx.dmg cures FPC configuration and now FPC
works correctly again.

It seems that this problem doesn't appear on Intel Macs. Only on M1
Macs.

Maybe OS X reapplies some security policy/permission every update?

Yes, but native ARM compiler continue to work.

Probably Jonas can check this issue on his M1 Mac?

I have not had this issue on my M1 Mac mini which I just this morning
updated from 11.5.1 to 11.5.2. I have FPC 3.3.1, 3.2.0 and 3.2.2 all
installed and the compiler binaries all still execute without any
issues (both native aarch64 and x86_64).

Interesting. I had this issue twice after updating to 11.5.1 and
11.5.2

My macOS installation is a clean (without Time Machine or import) when
I purchased Mac Mini M1 in March.

I did exactly the same as you, started completely clean with no TM
backups or settings migration.

Does the system log reveal more details about why the x86_64 binaries
are no longer being executed?

Sorry, I didn't explore system logs.

If this issue will occur again with future update of macOS, I'll try
to check logs.
