Like OS X 10.6 Snow Leopard, Lion requires an Intel-based Mac, but it goes two steps beyond that.
As a convenience, Apple allowed users to bring their Macs to a nearby Apple Store and use Apple’s WiFi to make the download.
Your mac os x startup disk has no install#
You must have OS X 10.6 Snow Leopard installed to purchase, download, or install Lion, and the 4 GB download could take some time with slower DSL connections (we don’t even want to think about how long it would take with dial-up). Lion was only available by purchase and download from the Mac App Store, where it retailed for US$29.99.
Some of these changes were to make it easier for iPhone, iPad, and iPod touch users to adapt to the Mac, some to make the two platforms work better together, and some to keep making the Mac better and better. N.OS X 10.7 Lion was released on Jand made some huge changes to the Mac. To exit single-user mode type reboot then press Return key and now your mac will boot as usual. This will take a little bit, based on the size of the disk, but the mac’ll be up and working after the repair disk permissions completed,just reboot and you are now ready to go.Ĩ.) If the disk in question is your Mac OS X startup disk ( or only disk as in my case ) and your computer stops starting up at the blue/gray screen, restart with ( Command+S ) keys held down so that it will take you to single user mode or verbose mode (as shown in the image below), and enter the following commands at the root prompt : Select “Repair Disk Permissions” to fix the issues.Verify disk permissions to make sure about the permission issues.Find your Macintosh HD drive in the list on the left, select it.Once the recovery partition boots up, go to the menus and select “Disk Utility”.One of your boot options is “Recovery” – just pick that.

The bar comes up on the bottom of the screen but goes away, the OS just hangs at the gray screen.ģ.) I have even tried running a couple sudo commands in the terminal as follows, without any success as sudo commands are not being recognized.Ĥ.) Another solution is a full reinstall of OS with a subsequent restore from one of my Time Machine backups.ĥ.) An alternative solution would be to acces the computer in Target mode from an other computer using a firewire cable and reset the permission on the drive.Ħ.) You can also startup the mac from an external recovery drive and reset the permissions.ħ.) You can try the following inbuilt feature on mac as well (as shown in the image below) : It didn’t work and still gave me the gray screen.Ģ.) I have also tried starting into safe mode. ( Above image shows the default permissions set for your Macintosh HD so don’t change )ġ.) I restored from a Time Machine backup from the same day I changed the permissions,but from an earlier time. I restarted again and now I’m stuck at the gray screen with the apple logo. Unfortunately, I did not know that changing it would effectively lock out the mac all together and the drive then turned into a blue folder with a red circle on it and just the gray screen of death with the perpetual wheel after reboot 😦 Actually,i was trying to change the permissions on my mac book air so that my hard drive would not be visible to everyone that could access my network share. Out of curiosity, I set the permissions on my hard drive from “ everyone” to “ no access“.
