MacBook pro 17 in. 2008, dead wifi after update

I installed lion from the app store. Wi fi died immediately. Later, eternet stopped working. These both corrected after I restored Snow Leopard, but I lost my lion restore partition in doing so. $30 mistake.

I'd second the resetting of the PRAM/NVRAM.
Restart your computer, hold down the Command/Apple-Option-P-R keys till you get the 2nd chime.
Release the keys and the computer should boot up normally.
The PRAM reset on intel-based Macs resets the NVRAM also, so you may need to reset the clock and volume settings once you're logged in.

New Retina MacBook Pro does not find WiFi after booting

My Retina MacBook Pro keeps looking for WiFis after it has booted, but does not find any.
I have to explicitly turn WiFi off and on again after booting to get it working.
When I put the MacBook to sleep and wake it, the problem does not occur.
Any hints what could be the problem?

Not sure if this will help, but you can go into System Preferences > Network and, if you haven't already, create a new location (mine is called "home"), then from this location remove all connection methods from the left column except Wi-Fi. Also, click on "Advanced" and remove anything from the Preferred Networks list that you aren't using. Then click on "OK" and "Apply".

New Macbook Pro does not start up after updating...HELP!!!

Hi,
My new Macbook Pro does not start up after it got updated. The first time I used it, it was perfect. I updated it and restarted it when it told me to but it doesn't boot. It shows an apple and a spinning circle when it turns on but that's it.
Can somebody please help me?

You should probably post your question in the MacBook Pro discussions:

Macbook Pro can't find Wifi after closing

I moved house and got a new wifi provider. My Macbook Pro can't find it sometimes after I close my Macbook which forces me to restart for it to join the network automatically. SOMETIMES I get a popup window with networks that it picks up and SOMETIMES my network is listed and I can select that, but not all the time. Why cant my Macbook find my network sometimes? It can find everybody elses except mine!

MacBook Pro won't boot up after updating to Lion

I just updated my MacBook Pro to Lion. After install restart the computer is stuck on the white screen with the apple logo and spinning wheel. I manually restarted it after 1 hour but that didn't solve the issue. What do I do? Any advice would be greatly appriciated.

That sounds like the case. Good Luck.
check this link:
http://lmgtfy.com/?q=Lion+boot+disk
there is a ton of information, step by step. I am sure there is probably something here in these forumns on creating the boot disk.
Again I would start with a clean install of Lion off of the boot disk you create.
FYI I started with Snow Leopard time machine backups updated, then cloned my existing drive to a FW drive before installing. During the work day and in IT, It was a savior to target boot from the firewire drive to address employee needs when I was having Lion lock up issues from the initial install.
Wipe and install clean so far so good. No lock ups. And USB flash install was super fast. Then brought my apps over, or re-installed. This way everything was clean.

Macbook Pro boots to Darwin prompt after update

I updated my Macbook Pro using Auto Update this morning, and now I can only boot to a Darwin prompt. The computer would boot, go to the starting OS X screen, then straight to the prompt. If I exited the prompt, I would be taken to a user login screen (which would revert back to the prompt after an attempted login)
I checked the system log and it showed that SecurityAgent was crashing.
So, per the advice in this post:
http://discussions.apple.com/message.jspa?messageID=1545778#1545778
I renamed the NetInfo Database, and reran the initial setup using the proper account short name.
However, now the computer goes to the gray timer circle before straight to the prompt, no Starting OS X screen.
The system log now shows the following:
loginwindow[66]: Login Window Started Security Agent
loginwindow[66]: AuthorizationRef doesn't have a username (<LoginAuthRefMgr: 0x336150>).\n
launchd: onoption repeating too quickly on port /dev/console, sleeping
I thought flushing the NetInfo Database would help, but apparently not.
I would appreciate any help, and thanks!

I am having the exact same issue!!!! The problem started as soon as I updated to 10.5.4. I sent my computer off to Apple's Depot to be fixed. The 6 day turn around really slowed me down. After my MacBook Pro was returned I had a note from Service that my Logic Board was replaced and my 3rd Party RAM was not 'Apple Friendly.' The RAM is fine and in Perfect Working Condition. I am assuming that after the Apple Techs got to my RAM they did not proceed to replace my Graphics Card or the Inverter Board (the small cable that sends power to the monitor). I took my MacBook Pro out of the box, re-inserted my 3rd-Party RAM and the computer worked fine for 3 weeks. That's until Last Night I had a FireWire Drive Mounting issue and had to Hard Re-Start my system it was then that the Black Screen Issue started again. Again, your notes are EXACTLY the same issue I am now having! I have called Apple Support and they will now take my computer to service with 'White Glove Treatment.'
After reading your post I am convinced that this is a software Bug. Apple please update. As of now I cannot even startup my computer to check for updates! Also, I cannot afford to be without my system for another week!!

Macbook Pro doesn't shut down after update

After downloading the update for Safari 5.1.2, I restarted my computer to finish the installation but it stayed stuck on a grey screen with the software update bar on top. Now I can't shut down my computer. Everytime I shut it down I'm brought back to the same grey screen and nothing other than the power button will shut my macbook down.
I'm running Lion on a Macbook pro 2.4 GHz

How long are you waiting? I've waited as long as 3-minutes in Leopard already. I was about ready to force shutdown, but then all of a sudden, it shut down.
If yo don't reboot that often, you may have a bunch of virtual memory swap files it's unloading. Try shutting down right after a reboot and see what happens.

MacBook Pro (early 2008) not sleeping after 10.6 upgrade

I upgraded my early 2008 MacBook Pro to 10.6 on Tuesday in what appeared to be a seamless upgrade. Everything works perfectly afterwards except that it now no longer sleeps when left. It will sleep when put to sleep or when the lid is closed but no longer from the Energy Saver settings. I've done a PRAM restart, tried it on power, on battery, with and without drives and networks connected but it stubbornly refuses to sleep. It ALWAYS slept reliably under 10.5 and nothing has been changed apart from the OS upgrade. I can see no untoward processes running in Activity Monitor and am at a complete loss to explain this very frustrating behavior. I would appreciate any help as this has completely ruined an otherwise faultless upgrade!

Hi-
I had the same problem. Open console in the utilities folder, and look to see if there is an epson file that it is trying to launch. It should look something like this:
9/9/09 5:13:47 AM com.apple.launchd.peruser.501216 (com.epson.epw.agent93833) Exited with exit code: 1
9/9/09 5:13:47 AM com.apple.launchd.peruser.501216 (com.epson.epw.agent) Throttling respawn: Will start in 10 seconds
9/9/09 5:13:57 AM com.apple.launchd.peruser.501216 (com.epson.epw.agent93834) posix_spawn("/Library/Printers/EPSON/InkjetPrinter/EPW/IJEPWAgent.app/Contents/ MacOS/IJEPWAgent", ...): No such file or directory
Snow Leopard changes the epson drivers in /library/printers/epson/inkjetprinter/... to /library/printers/epson/inkjetprinter2/..., and deletes the files that the computer is looking for. The easiest way to fix this is to go to epson's web site and find the driver's download for the picturemate dash (PM260). Under there you will find a universal updater for 10.6-10.6.x. Run this installer (file name is epson13044.dmg) and then restart. Check the console to see if it is trying to launch the file, but you should be good (if this was the source of your problem.)
Hope this helps, and let me know if you have any more questions.

My macbook pro won't start up after updating it

I Have a macbook pro with Mavericks (I don't remember exactly which one) which I bought in 2012, yesterday night I updated it and it restarted but it took forever and I thought it was installing something, so I left it like that all night and day and is still in the gray screen with the apple logo and the wait spiral. I got worried so I entered the disk utility option and checked the disk, and it said everything was Ok. When I restarted it again, the gray screen never left so I tried with the "safe rebooting" ctrl + cmnd + V and the screen shows now endless rows of "disk0s2: 1/0 error." and it's been like this for about half an hour now, I'm really worried I'll my data.

An 1/O error cannot be repaired by Disk Utiity.
That requires a more robust disk utility such as DiskWarrior
You can contact the developer using their email address here.
Best to get their recommendation before purchasing.
Hopefully you have a backup to restore from once the drive is either repaired or replaced.

MacBook Pro failure to start up after update.

I updatd to the new apple software to my MacBook Pro and on its restart it loads to the point that it shows the apple symbol with a progress bar and then shuts down before I can get to the home screen. Have attempted a restart on 3 or 4 occasion with no success.
I have also attempted a genius bar appointment with no success due to no availability of appointments.
Any help would be appreciated?

the following happens every time:
Starts up with apple logo
Shows my profile, I click and type in password
Apple logo stays and a loading bar starts (update progress?)
Bar progresses about 5% and stops, progress disappears,, MacBook shuts down.
Two possible issues.
1: Failed firmware update
2: Corrupted OS X boot and the at boot fsck drive repair can't fix it.
Run through this list of fixes, hopefully you have backups of your data off the machine.

24-inch Cinema Display and Mid-2010 Macbook Pro - Cinema Display still flickers after updates

I currently have a 15-inch Macbook Pro (mid 2010) hooked up to my 24-inch Cinema Display. I have updated all the firmware for both the Cinema Display and the Macbook Pro but still get intermittent flickering. Moreover, I have cleared the PRAM and VRAM. I have done ever possible update I can find, the system is fully functioning. Help?

I am having this exact same problem. 2010 iMac with NVIDIA GeForce 9400 256MB. I have it hooked to a 30" display through a DisplayPort to DVI-D adapter. The 30" is fine, but I have graphical corruption constantly on the main iMac screen.
This all started as soon as I updated to Yosemite a couple days ago.
