I just installed a OWC generic battery for my MacBook Air 13" - 2011.
It starts up but now it won't install the OS.
It pops up with:
macOS could not be installed on your computer
An error occurred while updating firmware.
Quit the installer to restart your computer and try again.
which I did to no avail, the same pop up.
Any suggestions?
I didn't think installing a new battery wipes the laptop?
MacBook Air
It can be done as @ SandsOfArrakis mentioned BUT whatever version of macOS is now installed ?? it will attempt to download and install the same version of macOS. Since it appears from the first post, High Sierra was trying to install thus something Older macOS must already be on the drive or it would not display " macOS could not be installed on your computer " " an error occurred while updating firmware "
In my opinion, there are two (2) methods to wipe and clean install High Sierra ( last version compatible with this MBA 2011 ) Boot in Internet Recovery Mode ( Command + Option + r ) immediately upon boot up. Will require a stable and fast internet connection - ethernet is best. Once in, in Tool Bar at Top >> Utilities. On left side point it to the Upper most Drive usually APPLE SSD XX. Select it and Tools at Top Erase as HFS (Journaled ) and GUID Partition Scheme. Once done, back out of DU and presented with Install macOS. It will download the most recent version of macOS compatible with this machine. It will download and install then reboot and do the System Setup.
The other Option is have another Mac compatible with HS. Open this link in Only Safari. Read all the details to create a bootable installer of High Sierra. Once downloaded, stop there. If the installer opens, just close it. The earlier link will also show you how to create the installer. This method is better in my opinion

I formatted it as Mac OS Journaled, the partition option was not highlighted for me to enter.
Originally I dragged the 'InstallmacOSX.dmg into the usb.
This time I tried to open the .dmg and destination install it in the usb...
I'm obviously not good at this stuff, but trying
Great, now it appears I've installed Lion, not El Capitain on the usb drive, meaning the pc needs access to the drive to open the apps etc.
So I went back with holding down option and start and I get these two options....
I take it the internal Drive was wiped clean before it was opened to self install the battery? If so, what method is being used to install the macOS? Is the computer connected to the Internet at the time of installation?
No it wasn't wiped clean. I followed the video instructions for installing the battery by first shutting down the computer, after installing the battery I turned it back on and that's the pop up I got.
I do know for certain, my machine circa 2011 MM had El Capitan and I wiped it clean and USB installed High Sierra. Immediately upgraded the Boot ROM. In my case, the machine was connected to the Internet at the time of installing.
I did all that, no good, says it was installing for the next 11 hours and then it came up with a pop up saying missing components.
At first it tried to install High Sierra, but I got the missing components thing, then it tried to install Lion from recovery I guess. But still no good.
Now I've downloaded El Capitain on a usb drive, plugged it in, held down the option key while starting the Mac hoping it would give me the option of Macintosh HD and Install macOS El Capitain, but it didn't just went into recovery mode. I heard I should go to the top and allow Startup Security for the usb but that wasn't there, Firmware Password Utility was.
Now all I get is a Mac OS X Utilities box with: Restore from Time Machine or Reinstall Mac OS X (which doesn't work), Get help online or Disk Utility
Very frustrated and all I wanted to do was install a new battery
Please see the Screen Shot I am going to include. It is my desktop on old MacMini 2011 running High Sierra. To me it looks much like the screen shot you posted in the first post.
I tried to reinstall and got this far, so I went back and created a partition, and went back to reinstall but the option to click the U Usb still won't highlight.
I might be getting somewhere.......this is happening on the MacBook with the usb plugged in...
What version of macOS is Installed before this error pop-up happened? What version of macOS were you attempting to UpGrade to?
I believe it was Lion 10.7
I wasn't even trying to upgrade, I just wanted it to reopen as it was. I didn't believe installing a battery would be an issue.
Maybe because it's an old OS?
Agreed, it does look like High Sierra from what I attached. Where can I go from here? Erase and then recovery mode to reinstall?
You should be able to erase while in Recovery Mode. Since you'll have access to Disk Utility there as well.
Seems to me you have your USB stick formatted the wrong way. MacOS mentions it. And explains what you need to do :)
Installed a battery, now won't install MacOS
