[JoeDacillo]

Hi all,

I'm having a problem on updatung my Macbook air, i tried to update it but suddenly in the middle of the installation it says that it cannot be installed on my computer.

My old mac os version is sierra and i'm upgrading it to mac os high sierra.

Thank you in advance!

Hello and welcome.

-Do you have a Time Machine or other backup of your data?
-If you restart, does the installer resume, or does it startup normally into Finder?
-Which model Mac?
-Do you have third-party RAM installed?
-How much free space is left on your drive?

Hi Cory,

- I don't have a backup data

- after I restart it will start again to boot and load the installer but after a minutes of installing it prompts me that it cannot be installed

- its a macbook air 13" inch 2013 model

- i don't have 3rd party ram installed

- from the time that I am installing the new os update i have 44gb left

I hope this info would help you to help me what i am gonna do next.

Thank you very much

It goes again to installation of Mac OS High Sierra, after I select restart.

OK, thanks for the additional information.

I would try restarting into safe mode to see if it will finish the installation:

Use safe mode to isolate issues with your Mac

Let us know if that works.

Hi Cory,

I hope it will continue on installation via safe mode, i will try that first and let you know.

I know what's the cause why the installation can't go through, I will just let you know about the updates.

Thank you very much I really appreciate it.

Hi Cory,

Just to update you I cannot proceed on safe mode when im holding the shift key it is just looping to boot screen.

Here's what I did to make my macbook air works again:

Shift + option + command + r to update my os back to when it came which is OS X lion

I'm planning to update it again to mac os sierra (but not to high sierra)

Thank you Cory
