detect_installed_32_bit_apps.sh not working on 10.15.7 #82

Closed micmil closed 2 years ago

micmil commented 3 years ago

I am having trouble with the script detect_installed_32_bit_apps.sh running on macOS 10.15.7. It does not appear to be detecting any 32-bit applications in the Applications folder. Have two 32-bit apps in the folder currently. I verified they are detected by System Profiler by pulling up the list manually. Both apps are listed correctly as 32-bit. Running the script does not produce any results.

Does it produce an empty file at "/private/var/log/32bit_apps_installed.log"?

micmil commented 3 years ago

No it says "No 32-bit applications found in /Applications, /Library or /usr/local."

aduffner commented 3 years ago

Okay, I looked into it. The script does a simple grep for "64-bit (Intel): No" and forwards the result of the command "/usr/sbin/system_profiler SPApplicationsDataType". You could look at the result of the command to figure out how to find a more reliable way. The script was edited 2 years ago, so of course apple may changed something.

I think I got it working. Looks like Apple changed the output of the "system_profiler SPApplicationsDataType". This line needs to be changed to:

# get all non-64 Bit applications from the initial list ThirtyTwoBit_app_list=$(echo "$ThirtyTwoBit_app_list" | /usr/bin/grep -B1 "Kind: 32-bit (Unsupported)")

The previous grep was pulling lines after the application type; it now needs to pull only one line above. They also changed how the 32/64 type is output. I don't have an example of the old output, but here's an example of the new output on Catalina:

I have to get my Big Sur test box running first before I test it there (ugh).
