Possible battery issue? Try a complete charge cycle, or Apple Diagnostics before replacing. Safety shutdown related to AC or Battery overvoltage protection Check the magsafe on the MacBook for dirty, oxidized or burnt and remove MagSafe 1 to 2 or similar if in use. Try resetting the smc, if that doesn't work, check the fans/airflow on the iMac. Check battery cycles (may simply need replacement).Ĭheck fans/airflow/thermal contact and thermal paste.Ĭheck fans/airflow. Incorrect current value coming from battery.Ĭheck the battery connection. Incorrect current value coming from AC adapter. If on a USB-C model, try charging with the ports on the opposite side (to test port failure on one side). If so, check the logic board for oxidation or dust. Try to reset the smc, if not, check the memory if possible replace it to see if the problem persists. SO-DIMM Memory temperature exceeds limits. Try reinstalling macOSX from a clean install on an external drive. Same as -61, except the machine will restart automatically instead of shutting down. Watchdog timer detected unresponsive application, restarting the system. It could be the USB controller or another T2 related USB hardware issue. Retry in Safe Mode, investigate stuck applications, investigate startup programs. Watchdog timer detected unresponsive application, shutting down the system. On Mac Pro, this can indicate an electricity issue to the built-in power supply, or an issue with the power supply itselfĬorrupted system or storage, Do not continue using the system, or you may experience data loss: Backup data to Time Machine, completely erase the disk and reinstall macOS system. Multiple temperature sensors exceeded the defined limit. Try an SMC reset first or a battery replacement! On a MacBook, this could be a battery issue, or battery controller (logic board). Iresulting from a hard reset or shutdown, check the power button and make sure it is not stuck, etc.ĪC power supply failure, check power supplies: cables, plug, magsafe. Is it a 'clean' shutdown or hibernation by the user If while using the app, see if there is an update for the app by the developer, and leave a comment below with the app name and your Mac model.⇧shift If this occurs during boot, try Safe Mode by holding on boot to limit what opens during boot. So the only time you need to even run MalwareBytes is after you install something that did not come from the Apple App Store.Log show -predicate 'eventMessage contains "Previous sleep cause"' -last 24h Or the software author is being paid by an adware vendor to side-load adware with their product.īut in all cases the user had to actually intentionally install the software.

Either they think they are downloading something legit (like Adobe Flash), but are really on a malware webpage. All of it requires the user to be tricked into installing it. Plus MalwareBytes actually finds and removes stuff that affects Mac users.įinally, to date, there is no self propagating malware for the Mac. The Mac version was written by a long time forum contributor, and has earned the trust of the long time forum volunteers. If you want a package that has proven itself, then look at MalwareBytes. ![]() ![]() ![]() Worse most of them do not actually find anything that actually affects Mac users. Many anti-virus packages are badly ported Windows packages that they are trying to shoehorn into macOS and do a poor job of it. Then when the macOS kernel changes, these packages do not get what they expect and they are not doing what the kernel expects and often a panic happens. 3rd party anti-virus packages are at the top of that list, because they frequently do not use official kernel APIs, and just go roaming through internal kernel structures without taking the correct locks, or inserting code into kernel code paths to intercept some kernel operations. 3rd party kernel extensions are the #1 cause of macOS panics.
