I was trying to update my Mac to Mojave but when it was restarting it got stuck and all I see is apple logo. I am not sure what happened and how can I get back to start m Mac. Any help please.
This is what I see in photo below.

I assume that you didn't shut the lid down while updating it or basically didn't put it to sleep through anyway.
if you didn't, I just recommend waiting.
if still stuck, try reinstalling using recovery mode. which is holding CMD-R just after power up during restart . Apple support for reference
Maybe you have a problem with the internal private ram used by the system so it cant’ boot up. You can try this manipulation (2 or 3 times to be sure).
If it doesn’t work, try booting your Mac without extensions (as explained here).
If it still doesn’t work maybe you can try to install macOS from the recovery partition to an external hard drive and then boot up by maintaining alt before the Apple logo. If it works maybe you have a problem with your hard drive or the partition table (GUID) and if it doesn’t work it’s most certainly a hardware problem.
