Troubleshooting iMac Question Mark Folder

The main reason why your iMac could be showing a question mark folder is that your iMac is unable to access the operating system. If this issue is caused by software issues then you could either have corrupt operating system or no operating system on the storage on your iMac. In order to troubleshoot this issue you have to first check whether your iMac is able to detect the storage. In order to do that you’re going to have to first power off the iMac. Then you can power on the iMac whilst holding the option key on the keyboard or alt key when using a windows keyboard until you see a storage icon on your screen. If your iMac is not display any storage media and just showing wifi sign and choose network then it would mean your iMac is not detecting your storage. You can try NVRAM reset to troubleshoot this issue. Sometimes NVRAM reset fixes the problem. If you do see a storage device on your iMac then try selecting the drive and click on it or press enter after selecting the drive. If you have other bootable devices connected then you’re going to see a yellow icons there and those are devices that you can boot the iMac from. This could boot up your device sometimes. If you still see the question mark folder on your iMac, then you’re going to have to reinstall another macOS software on it. It is always a good idea to back up your drive before you install a new version of macOS on it since there is chances of data loss. You can use a bootable usb with installer file to install macOS on it or if you have a cloned version of your macOS, then clone it onto your internal storage by booting the cloned drive from the outside.

Q. How to reset NVRAM?

A. You can reset NVRAM on your iMac by simultaneously holding the keys Command, Option, P and R when you turn on the iMac. This could sometimes fix most of the software issues on your iMac.

Troubleshooting iMac Stuck On Apple Logo Bar

Is your iMac stuck on the Apple logo bar and not booting? Just like the question mark folder this could be because of corrupt operating system, loss of system files or due to nearly full storage on the iMac. In order to troubleshoot this problem, the first thing that you can do is try an NVRAM reset on it. Your problem could be solved. If it is still not solved then you can try to check the internal boot storage by holding the option key and selecting the boot drive and if it’s still stuck on the Apple logo then you can try to reinstall or clone the operating system from a bootable media. If all things fail then this is likely a hardware related problem.

Troubleshooting iMac Kernel Panic

Just like how on windows there is a blue screen of death letting us know that there are issues on your computer, the iMac has kernel panic screen which restarts your computer and makes it unable to boot. Your iMac could have kernel panic if you have tried installing a new version of macOS but still have older generation firmware, broken disk permissions, incompatible or corrupt applications, insufficient RAM, outdated drivers or hardware issues. If you have issues with disk permission then you can go into recovery mode by holding Command + R when you power on your iMac and it will display disk utility icon where you can select your boot drive and click on First Aid disk permissions. If this does not solve your problem then you can try fixing this issue by updating your macOS or installing the macOS compatible with your iMac model and year. Sometimes even having your disk on full capacity could be causing this issue, so if you can sort out your storage then it could also fix your kernel panic issue on iMac.
