10.7.4 update anyone else having issues not being able to boot after install ?

I used the apple update link and no issues. It took a short period of time only. Rebooting went well. I do have a cable modem with 20 mb download speed. Wonder if the download to your system got corrupted some how. Can you try again ?

What system do you have ?

What iOS was originally installed on that system ?

 

Do you have a BootCamp partition? Sounds like it's trying to boot from that, because you'll never see a black screen like that when booting a Mac otherwise.

Try holding Option at startup and see if you can choose to boot from your Mac partition from there.

Amazing!

I just updated my Macbook Pro 13 inch early 2011 yesterday and im shocked at how snappy it is now. I bought a refurbished mbp a few weeks ago 4gb of ram and everything was pretty much laggy and slow. Preview and iphoto took forever to load and safari constantly froze and lagged out so i switched to chrome. After this update i dont have any problems. Before i used to have to force quit if i had itunes and chrome opened at the same time, now i can run anything i want with no lag at all!

 

hmm, maybe I should wait for some days before update

 

Just updated iMac (2012) and MBP (late 2011), no issues.

 

I just did my 2011 13" MBA, and like you I experienced a great result.

Fortunately I have a fast broadband feed, and it was a very fast and easy upgrade.

 

I just updated my 2010 MBP. No issues. It booted just fine after the update and seems a bit snappier at first use.

 

Bootcamp Issues

I encountered a similar issue. After upgrading to 10.7.4, my Bootcamp partition won't load. (It loads, as the poster above described, to a black screen, where it freezes.) I talked to another user on Twitter who experienced the same issue; although, he was able to boot from Parallels. I hope Apple takes note of this and issues a fix soon, as this could be a big problem for a lot of users.

 

Open System Preferences > Startup Disk and choose your Lion partition and it will keep it as default.

 

10.7.4 updates probably the partition layout. I think you can repair it with a 64-Bit Windows 7 boot-DVD. 64-Bit Windows 7 supports GPTs.

This helped me on a mixed Windows 7/Linux installation (Linux modified the partitions), so it helps probably if you have Windows/Mac OS X boot loader problems.
