Macbook Pro Retina - doesn't connect to Internet after "hibernation" but works fine after a complete shut down.

This is a new occurence and is not tied to the Maverick update.
When I close the top of my laptop and reopen it (whether 10 minutes or overnight) and click on the Safari icon - I get my Safari opening screen - but each tab says (Fails to connect). No problem if I shut the machine off and then restart it. Connects right away.
As this is not tied to any upgrade or addition of any software or change in the router - I suspect I may have inadvertently changed something and I'm at a loss. Has anyone seen this and figured out what stupid thing I may have done? I never go into registries or anything like that and I would be uncomfortable doing that - particulary because I have a fix - just shut down the computer completely after each use.
Thank you in advance....

If it's a network that requires a password, just a hunch, but I'd try this even though it says WPA2 and different symptoms & HW, wish Apple would update that doc, as many other reconnect problems get fixed by it...

Not certain if this has helped anyone past 10.4.10 yet though. A static IP helped some.

My macbook pro retina doesn't connect to my office's wifi

I have my mac for a month now. It used to work a little bit but when I lost it I just restart my mac, but now it's not working at all. I don't have any problem getting access to any other network beside the one at my office. I can see the network but I'm unable to do anything with it. I read that I need to reboot the modem but it's impossible for me to do that Since there's a lot of other computers using it and I'm the only one with this problem.

Remove the WiFi profile in System Preferences/Network and reset up the connection.

I could be *very* wrong but did not know you could output from HDMI into displayport consistently with no issues.
Try a mDP to DP cable like this (the mDP end will go directly into the thunderbolt port of your laptop)

I have an email account causes the machine to hang up after being in use for a day. It only occurs on my Macbook Pro and only one particular account. The problem account works fine on my iMac and Windows Machines. Any ideas what is causing this?

I have an email account causes the machine to hang up after being in use for a day. It only occurs on my Macbook Pro and only one particular account. The problem account works fine on my iMac and Windows Machines. I have been to the local Genius bar and through trial and error we have determined that Mail is working ok but somehow the account is causing the problem. I have used this account for years. Any ideas what is causing this?

No idea why, but one thing you may try if you have the time, is create a new user, and set up the problem mail account in the new user space. See if it causes your MBP to hang as well. That will tell you if it is something wrong with your main User, or something wrong with MBP.
Assuming this works, I'd nuke the problem account in your main user space, re-start, and reinititate the account and see if that helps.
Depening on how many email accounts you have setup, it may be necessary to nuke the whole Mail folder in your User/Library.... Hard way to get it to work, but just my idea.

Macbook pro had coffee spilled on it 2 weeks ago, all works fine except monitor display.

Macbook pro had coffee spilled on it two weeks ago; all working fine now except for the monitor, display is dim and photos not appearing properly. Any suggestions? Apple said would cost too much to repair, anyone had any luck with outside repair facilities? thanks.

I would check with HP. Your scanner may need a firmware update and updated HP software. Start here:

Welcome to Apple Support Communities
Your hard disk is damaged. Make a backup of your files with Time Machine > http://support.apple.com/kb/HT1427 Alternatively, you can use Carbon Copy Cloner to make a clone onto an external disk.
Then, look for a hard drive. You can use a 2'5" SATA hard drive, and you can buy it at OWC > http://eshop.macsales.com/shop/hard-drives/2.5-Notebook/ Seagate and HGST drives have good performance, and 7200 rpm hard drives will give you a slightly better performance.
After installing it, start up from the clone (if you made a clone) or hold Command, Option and R keys while your Mac is starting (if you created a backup). In the second case, you just have to choose the option to restore a Time Machine backup and follow the steps.
In the case of a clone, use Disk Utility's Restore feature to restore the external drive content onto the internal disk > http://pondini.org/OSX/DU7.html You may need to format the hard drive in "Mac OS Extended (Journaled)"

WRT1900AC and Macbook Pro Retina - refuses to connect with Wireless N

I have the first generation Macbook Pro Retina, and just recently upgraded my D-Link D-655 for the Linksys WRT1900AC. I also put the router on the first floor (the D-Link was in the basement) because there were some huge holes in wireless coverage I hoped to fix.
To my dismay, the thing will not negotiate a connection with ANY wireless N device as wireless N. When I set it to wireless-N only on 5 GHz, nothing will connect to it, and same with 2.4 GHz. My macbook's system report shows the network as being Wireless G on the 2.4 band and wireless A on the 5 GHz.
I have 50 MBPs internet here, and when I plug directly into the router, I get that. However, I am maxing out at 20 MBPs over wireless with both my macbook and my Samsung Galaxy S4.
I'm about at wits end, my next step is to return this thing. I have been on hold with support for 20 minutes, which is freakin eerie because they have no hold music or talking so it's just dead silent.
This morning I spent an hour on a live chat with support, and nothing she had me do made it better, and in fact any changes made it drop from 20-21 MBPs down to 16-17 maximum.
On her advice, I re-installed the firmware, downloading from online, and this had absolutely no effect. Any other ideas to try? I get these crappy connection speeds sitting 3 feet away from it. I live in a house, so no massive interference from neighbors (only 2 other wifi networks are visible)
Solved!
Go to Solution.

let me be clear here: I had the same slow speed with both my mac and my galaxy s4, it is not a mac problem. I had disabled media prioritization and the WMM thing in the settings for media prioritization. Yes I am sure I am connecting to the right SSID. The old router is DIR-655. Part of the reason I wanted to upgrade is it disconnected my galaxy s4 every 2 minutes (and many people have had that problem, a quick google search verified that the router just doesn't like galaxy s4). OS X 10.7.5 but as I said my Galaxy has the same issue - it does not connect as wireless N, and when I make the router Wireless N only, not one of the computers in the house can connect to it. That includes a Mac Mini, Galaxy S4, Macbook Air, Macbook Pro Retina, and a Chromecast (which only works on the 2.4 band, but same issue there).

Macbook pro retina display wifi connection problem.

Macbook pro Retina display - 3 weeks old - connects erratically to home wifi over Airport Express
iphone and iMac connects to the same wifi network. I am connecting through iphone hot spot to write this question. please help.

I have posted my solution i.e. update airport utility software. Ocourse you needa working internet connection for that!
I have a 27 inch imac, mac book pro, mac book pro with retina display, iphone 4, iphone 4s, 2 x iphone 5. Each device was showing erratic internet connections at some point in time or the other.
I just updated Airport Utility Software. You can find it in Applications/Utilities. When you click on Airport utilities, it opens a window with 2 icons. The bottom icon will look like your airport express. click on that and then you will get info on the right. If , I repeat if, your Airport utility software requires updation, you will be prompted in the info box. Click that and then you will be fine.
However, the irony is that you need an internet connection for this. I set up a hot spot on my phone and did it.

Anyone having issues with their MacBook Pro Retina losing network connections?

I have been having a problem in which my internet connection, which will be working normally prior to closing the Mac, will not reconnect after it's woken up. I have to go so far as to reset my Time Machine AND Macbook to restore the connection. I noticed the most recent update for Mountain Lion also included some mention of a specific patch for Macbook Pro Retina's. Does anyone know of a documented issue?

Some recent updates from Apple might affect your problem, but I can't be sure. How long have you been having the problem?
I have to go so far as to reset my Time Machine AND Macbook to restore the connection.
Don't confuse "Time Capsule", an Apple Wi-Fi base station, with "Time Machine", backup software included with OS X since version 10.5. Your problem involves the former, not the latter.

Macbook pro retina doesn't turn on for a day or two

Macbook Pro Retina 13-inch Late 2012
2.5GHz Intel Core i5
OS X Yosemite (10.10.2)
So this is a weird one... I recently purchased a used Macbook Pro Retina and the previous owner had upgraded the hard drive for a bigger size. My macbook worked great for a few days but then one night I closed it and the next day when I opened it, it would not turn on. I tried rebooting the battery (SHIFT+CONTROL+OPTION and POWER) then hitting power but NOTHING. At one point, I heard a clicking sound when I would leave the power button down. Then... two days later I push the power button just because and BAM! The screen comes on. (I didn't hear the start up sound, and it wasn't like it restarted.) It was as if the screen brightness was all the way down but then came back. (I kept trying to adjust that too before it turned on).
I don't understand!!! Two days later, same thing happened. Then again, it turned back on a day later.
The only thing I noticed that was weird was when I connected it to my tv with HDMI cable. The laptop screen would freeze and get distorted and I would have to force a restart (the black screen with the apple would appear and the loading bar as if I would updating the software).
I'm soooo confused and I don't want this to keep happening. I would appreciate any type of help or advice!!

Macbook Pro Retina doesn't see internal SSD drive

Hi Guys,
I have a problem with my Macbook Pro Retina 13(late 2012). Yesterday I've done clean install of Yosemite. Everything worked fine, and I wanted to restore my files using Time Machine. So I restarted it (command +R), plugged in my extertal hard drive, turned on TM restore option and chose my SSD drive as a place to install. Mac asked me to enter password for the SSD (default filevault2 in yosemite), I entered the password, system accepted it and then something went wrong. System told me to restart mac and try again. I restarted it, and did like previous but this time, my mac stopped to see his internal SSD drive. System was asking where to install yosemite form Time Machine and there were no drive to choose. I turned on disc utility, and I see my SSD drive there but I can't erase it, or unlock (picture in appendage). I can only verify disc and it shows that drive is fine. I've tried to install Yosemite on my external drive and boot from there,to unlock SSD in settings(I've chose my Ex. drive as a place to install Yosemite) but it didn't work. I even tried internet recovery (command+option+R) but I didn't help, SSD drive was still useless.
I think my SSD is still locked, but I don't know how to unlock it now. I don't need to use Time Machine anymore(I have my files in other drive too). It can be clean install but please, can somebody tell me what to do? I have exams this week and really need a computer :<

Start your mac up by holding the alt key. That is boot from function.
If its empty then you might have a hard drive issue. Due to your hard drive being picked up but not the partition on the drive. This will most probably be a OS X reinstall.
Erase the drive and reinstall the OS X or run a recovery mode.
Good luck

My new macbook pro retina won't connect to my iPhone 4s via bluetooth

Just bought macbook pro retina. have had iPhone 4s for two years and use it to tether my iPad to regularly no problem. however the macbook pro won't connect to the iPhone via bluetooth. it recognises it's there and a connection code is displayed, but when I enter the code it won't connect and the phone insists that I agree to 'forget this device'. how do I enable tethering so I can use the 3g signal to browse on my laptop whilst travelling please?

Only thing I could suggest would be to "Reset Network Settings" on the phone (Settings> General> Reset>) . Of course, this will forget and delete any saved Wi-Fi or network configurations, but if that's not a problem for you then, maybe worth a shot.
Although saying that, I think iCloud remembers old settings (if you are connected and sharing network configurations), so may not be a total loss.

My brand new Macbook PRO i5 can't connect to internet after sleep? It works fine after reboot.

I have a brand new Macbook PRO with the latest OS and the latest EFI. I haven't installed any 3'rd party products except Moneywell for my private finances. After a couple of days it couldn't connect to internet after sleep. I run the network diag and it says the connection is OK. Log out/in doesn't help. I have to reboot everytime it wakes up after sleep. Any clue?
br,
DAVID

I am having the exact same problem. It started with 10.7, was fixed with 10.7.1, then came back again with 10.7.2.
