Downloaded and installed os x yosemite and now mac book pro will not restart? How long should this take? Is there something wrong? Please helpthanks in advance
MAc book pro. I have downloaded and installed os x yosemite now mac book pro will not start? How long should it take? Is there something wrong?
The 2 computers here took about 45 minutes to an hour each.
The best thing to do is give it more time. If it gets too ridiculous, shutdown using the power button and then restart. Check menu/About This Mac to see if it is installed.

Help! Installing updates an error occurred now my MacBook Pro will not restart. "Unable to find driver for this platform"
Did you try more than once? If so:
Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
Reinstall Mountain Lion or Mavericks
OS X Mavericks- Reinstall OS X
OS X Mountain Lion- Reinstall OS X
OS X Lion- Reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet
if possible because it is three times faster than wireless. -
My iphone froze this morning when trying to install updates, I had to restore it to factory settings and then chose to restore it from my back up information. It now shows "Restore in Progress" but nothing else - this has been going for about 80 minutes and I'm not sure if it has frozen again or if it is actually doing anything.
Can anyone please advise?iOS: Unable to update or restore

I've erased and formatted the hard drive accordingly in order to reinstall OS X. everything went fine until about half way through the install. it just seems to stop. how long should this take? should i do something else to speed it up?
About all you can do is wait until it finishes or you get an error message.

Bought and installed a new battery for my Mac Book Pro 5.1, intel Core 2 dual, the computer makes a lot of engine noise! The noise disappears in sleep mode. What can be done?
I bought it from Other World Computer last week for $95. 3rd party, I suppose.

I have OS 10.8.2 and use wireless at home just fine.
When I visit a friend with only a cable modem internet my Mac Book Pro will not connect.
I see that the Mac Book Pro is picking up the internet when I check the internet preference section but it will not open Safari.
What do I need to do connect via a cable modem?You need to power off the modem for 15-30 seconds, then power back up and then connect. The modem is remembering the last connection (your friend).

My mac book pro will not fully boot up. I have the grey background with the apple sign and the timer going round...but 20 minutes later still no desktop
You could try doing a hard shut down (holding the power button or yanking the battery) and then doing a safe boot by holding the shift key at startup:

Also, not sure if this applies in your case, but I've had that happen when there's a USB drive inserted either in the computer or a connected external keyboard. I did a hard shut down, removed the drive and it went through a normal start up. -

My Mac Book Pro will not start up. I ran the AHT and received the following error: 4SNS/1/40000000:Th0H-90.750. Anyone know what this means?
I have no idea how much it will cost to repair. I don't even know what the exact problem will prove to be. It may be quick if it isn't a motherboard problem. I just don't know. Take it in for a service diagnostic, then they can tell you what is involved.

My 2009 macbook pro will not boot up and I have tried everything to get it to work. Please help!!!!!!
Do you have an external drive? If no, then you will need to purchase a drive so you can backup your data.
If you have a drive that is formatted as GUID you can select to install OS X from recovery mode on the external drive. Now you can boot from that drive and make a backup of your internal drive so you can erase and reformat the drive.
Recommended Drives
USB 3.0 drives work on USB 2.0 but you do get 2.0 speed. They are cheaper because they are popular PC drives. If you get a new computer you'll get the bump to 3.0 speed. I don’t recommend FW. The newer computers don’t have FW ports. You would need a connector in order to use the drive on a newer computer.
Size: I recommend either the 2T or 3T drives. Often they are cheaper than a 1T drive. The 4T drives have more issues and failure rates.
Many drives come formatted for PC but easy to format in Disk Utility.
This Western Digital drive has good reviews: Has a 2 yr warranty. Comes formatted for Mac but I would still format using Disk Utility.
WD My Book Hard Drive for Mac 2 TB (WDBYCC0020HBK-NESN) $99
WD My Book Hard Drive for Mac 3 TB (WDBYCC0030HBK-NESN) $119.99
Check the warranty when comparing. The longer the warranty the better the drive. WD makes cheaper drives but with almost no warranty.
Locally, Best Buy seems to have the best prices. -
IMac and Mac Book Pro will not stay connected to WiFi on TC
Hi,
I'm a new Mac owner, and I changed completely over to Apple over the weekend. Have na iMac and Mac Book Pro with a 2 TB Time Capsule. Hooked everythng up and all seems to be working, except everytime my computers go into sleep mode when I wake them up they ask me to select my wireless network again because I lost connection. Once I select my network it works fine until the computer goes to sleep. WhenI wake it up, it asks me again. I have it set to automatically connect to known networks, but it doesn't. I have to click on it everytime I wake up the computer. Before I hooked up the TC, I was using my old wireless router and it stayed connected. Now that I put the TC in as my wireless neteork it asks me to select my network. Is there something I'm not doing that may help the iMac and Mac Book Pro stay connected?
Thanks.For that particular WiFi update, yes - it means you can't download it. However, that update may have been included already in M-L 10.8 ...
I feel your pain regarding these anomalies - I had the same problems on my year-old iMac that I just exchanged with Apple for a new one - I had worked these software/network issues on the old one for over five months, and finally, I demanded a new system as a replacement. Just too many problems. For me, Update 10.7.3 for Lion was the cause of my network problems. The WiFi update/patch solved the sleep issue for me, but not the auto-connect problem for system start-up's and restart's. After system start-up's and restart's, I would have to manually select my router address to connect via WiFi. But after manually selecting the address, the WiFi connection would stay-on - it wouldn't drop-off.
Again, with this replacement iMac, I don't even trust its WiFi capability - and with a desktop, why should I ? I simply purchased a Cat-6 Ethernet cable, and wired it into my Time Capsule ... To heck with WiFi ! ... Remember: don't download ANY system updates wirelessly ! Don't do it. ... Apple will rue the day they did away with Ethernet connectors on their computers ... - The same goes for CD-based software, or at least some other "physical" means for software installation ...
But, as for future system updates, and how they affect this new iMac ? - If they screw it up, I'm not messing with it ! - Apple's getting it back, the next day ! I'm not going to go through five months of testing, repairs, forced new purchases, etc. etc. ever again ... -
