NVRAM error in Tinkertool

[amitkool21]

What kind of error is this...?? Should I be worried...??

No, it just means your startup volume isn’t in your NVRAM right now.

How can we fix that...??

assuming you have NVRAM set up correctly, just follow the steps in the error message (select your startup disk in system preferences)

I already tried that,but it ain't working.

You may need to dig deeper and see if your NVRAM is working, but you can literally ignore that warning from tinkertool. It literally just means your Mac will scan for bootable volumes on each boot, that’s all.

Hmm interesting... I guess for the same reason clover screen is delaying a little bit.

As you suggested I'll dig deeper in that matter, but I'll really appreciate if you could share a good link to read on this issue.

@amitkool21,

On A hackintosh it does not matter that the startup drive is not defined in NVRAM ... its actually quite common unless you use something like EFI Agent :-

EFI Agent v1.3.2 (menu bar utility)

Simple, low resource, efficient and no frills tool to mount EFI partitions. Features: Shows EFI disks to mount / unmount and open in Finder Shows disk icons and color-coded partition scheme Shows boot EFI partition (uses IODeviceTree:/chosen/boot-device-path if...

On a PC you configure the Clover boot volume in the PC's BIOS .. which then boots clover, clover then boots MacOS as per your config.plist thus even if the boot volume variable is in NVRAM it is not used.

On a Genuine Mac the BOOT ROM EFI checks the NVRAM for the boot volume, if its missing it then scans all volumes and presents a list, On a Genuine Mac you set the boot volume via System Prefs -> Startup Disk.

As Tinker Tool is optimised for use on a genuine MAC it throws up that warning ... as it does no know it's running on a PC. You can safely ignore the warning ...

Cheers
Jay

@jaymonkey

thanks man, its clear now... you saved a lot of time for me.

But it makes me curious, because in earlier versions of macOS or OS X there was no warning by tinkertool.
