I have an Ipsw file on my macbook air is it now outdated?
I have Ipsw file that takes up almost 8 gb of my macbook, it used to be my uncle's before he passed so I have no way for me to know what it was for it says “iPhone12,8_18.1_22B83_Restore.ipsw”. I tried google and reddit to find what it is for and if it is able to be used or even know what is in the file but I cant open it due to the application my mac shows me is not available in my country, what do I do?
MacBook Air 13″, macOS 12.7
