MacBook Air repeated restarts due to a problem.

Question

MacBook Air repeated restarts due to a problem.

I have tried all suggestions I could find out there but have not been able to correct this issue. I have an older MacBook Air (2015?) and running latest OS Monterey 12.7.6. Any help is appreciated.

panic(cpu 2 caller 0xffffff80147044f0): __memcpy_chk object size check failed: dst 0xffffff86aa8134a0, src 0xffffff8b761d4e94, (1024 < 1884) @subrs.c:606

Panicked task 0xffffff8b7661d670: 176 threads: pid 0: kernel_task

Backtrace (CPU 2), panicked thread: 0xffffff950dd9b000, Frame : Return Address

0xfffffff2ccb337e0 : 0xffffff8014879a3d

MacBook Air 13″, macOS 12.7

May be a hardware memory failure. However, there is a chance some third party software is the cause. Run the third party app EtreCheck and post the complete report here so we can examine it for clues.

I suggest that you consider the advice that HWTech has provided you to run an EtreCheck report. Without any additional information it will be difficult for any of us here to assist you with this issue.

The restarting issue continued to happen after clean install of latest OS (Monterey). It would restart frequently within an hour.

I erased drive again but this time installed older version of OS (Big Sur) and had been up and running without restarting for almost 24 hrs now.
