Hi, I'm a new owner of Apple laptop since I always using PC. I'm an experienced perf user but now I'm happy having my MBP2021 laptop so I need to learn new tools. I found that xctrace is the new way to capture profiles on Apple devices so I've installed one and ran on my app. Unfortunately, I didn't manage to make it work. Here is my script: ❯ xctrace record --template 'CPU Counters' --launch -- ./target/release/deps/flower-b0a05df673ad26db tests::test_run Starting recording with the CPU Counters template. Launching process: flower-b0a05df673ad26db. Ctrl-C to stop the recording Target app exited, ending recording... Recording completed. Saving output file... Output file saved as: Launch_flower-b0a05df673ad26db_2022-05-09_21.02.47_4E6DC3F7.trace. ❯ xctrace import --template 'CPU Counters' --input Launch_flower-b0a05df673ad26db_2022-05-09_21.02.47_4E6DC3F7.trace Import failed with error: Cannot find matching importer for url: Launch_flower-b0a05df673ad26db_2022-05-09_21.02.47_4E6DC3F7.trace/ -- file:///Users/pzixel/Documents/Repos/flower/ I tried to find any information about to how to make it work but failed. I hope I can find some support here.

When trying to profile any process with the Instruments CPU Profiler I get this message: (Before run started) No allocated PMI record. Not sure what to do here. I tried other instruments like time profile and that works fine so not sure what to do here... Didn't find any people having similar issues when googling so I'm hoping someone here can help me out. Im using a m1 max 14 inch macbook pro with macOS 12.3 and instruments 13.0 (13A1030d)
