I accidentally deleted System/Library/Extensions on High Sierra using Terminal. Is it possible i can get it back? If no, what should i do next? i'm sorry i should've double checked and sorry for being jerk. Many thanks in advance.
iMac, macOS High Sierra (10.13.6), null
Simple answer is to reinstall your current OS by rebooting while holding CMD-R. This will reinstall the last OS installed on your Mac. Be sure you have a current Time Machine backup of your data prior to the reinstall just for good measure.
Thank you, but i don't have a time machine backup. Is there any other way to reinstall the current OS (High Sierra 10.13.6). Thanks again.
PS: My iMac is currently running without any sort of problems, so is it an issue to still keep on working or do i need to stop and reinstall the OS?
Do you have a backup disk?
The last time I did that I got an error: "Could not create preboot volume" and my computer wouldn't turn on.
No, i do not have a back up at this point. Please advice.
