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.

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.

Hi, I have a latest Macbook Pro Retina. I connect its hdmi port to a DisportPort of HP Compaq LA2205wg external monitor, but no signal at all. Could anybody help me

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)

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 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!!

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.

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 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

Original Macbook Pro Retina 15 not connecting to wifi after sleep

When Waking from sleep, it searches for wifi and finds it but doesn't connect most of the time. i click/select the network manually & sometimes it connects but iv ended up resorted to turning wifi off, then turn back on & it finds the network (it found earlier) AND connects to it automatically. this problem happens on other wifi's aswell, not just my home wifi.
Wondering why it can find the network after sleep, but doesn't want to connect to it. All my ios devices, my sisters MBP retina 13 connects perfectly. I've come to conclusion it must be my computer....

I to have this problem. I have a late 2013 Macbook Pro 13inch with Retina display. I soon discovered on my machine that if you disable Bluetooth then the macbook connects to the wi-fi as it should. I dont have a problem on my home network with any other apple devices and the connectivity issue is the same on what ever network I try. I soon realised that if I disabled Bluetooth the machine connects perfectly everytime. There is clearly a bug or some technical issue that occurs preventing wi-fi connection when you have Bluetooth enabled. Try it and see if it is teh same with yours?
I was hopeing that the fault or issue would be fixed with the latest OX update but alas it is still an issue for me on my machine. I have just taken to switching Bluetooth to off until I am connected and then just turn Bluetooth on if I need it.
Hopeing that some kind of fix will be issued soon.
Let me know if this Bluetooth issue is the cause of the issue as I woudl be interested.
Best wishes.

My new macBook Pro Retina won't connect to my wifi. Password IS CORRECT.

I just got a new-in-box retina MacBook Pro. It sees my wifi network--signal is max--but the base station will not accept the 100% correct password. Other devices have no trouble connecting.
I'm setting it up for a PC switcher. What an embarrassment!
We're trying to connect to a Time Capsule base station which I added to my system last week. No other devices have trouble connecting.
Suggestions?
--Jay

-->Try Connect to Other.
Done. Failed.
-->Try clearing the preferred network.
If I understand you correctly, there is no preferred network. It's a new machine, it's never connected to anything.
-->Please update your signature with your installed operating system for the questionable MacBook Pro, or indicate what Mac OS X version you are running, so we can tell you if there are additional things to look for.
Thanks for alerting me to this. I added some more stuff to my sig.
It's a new Retina MacBook Pro, running Mavericks 9.0. I just unboxed it this morning.

My Macbook Pro (retina) doesn't want to read an IDE with adapter?

I purchase a Sabrent USB 2.0 to Sata/IDE hard drive Adapter, as I would like to look at all the data on three old hard drives I've extracted from old PC's (which had Windows 95 - 98 I believe) as it's mainly just photo's and perhaps a few documents needed.   May be some .mp3 music files as well.
Now, I sit here with my Macbook Pro on my lap, the old Hard drive is humming nicely, the red LED showing on my adapter showing the USB is hooked up nicely to the Macbook....but if I open either Finder or Disk Utility nothing is showing up?
By what I can tell, the IDE HD is set as 'master' if that helps?
I'm not quite sure why there is an issue, but I thought some of you folks would be much more an expert on this than I, as I it just took me most of a day to figure out how to correctly put a new Samsung EVO SSD in my wife's 2012 Macbook Pro, where I then took out the optical drive and put a caddy with her old HD in it. I ran 'Carbon Copy' cloner, and all is good....albeit, I haven't yet eliminated the data on the Sata drive, as it asks me for a password to be able to do this, and I'm not sure if that is the correct way to delete all files and repartition?   So in reality, I guess I have TWO questions!
All three drives I have are from PC's, and are IDE drives from a Window based PC, so should my Macbook Pro be able to read these drives, and be able to copy the files I'd like to save/copy from it?   I'd then like to transfer them to my external hard drive (4 TB) which are mainly photo's of my kids when they where little.   Not sure if having the IDE set as 'master' is the issue, or if the data being Windows based might be it?   I'm new to doing this sort of thing, so I appreciate any advice you might have.
Thanks in advance!

MacBook Pro Retina doesn't show correct colour spectrum

I'm having trouble with my late 2013 13" MBPr display, it's displaying low colour spectrum, something like 16 bit colours. I took a photo of my screen right now, and it display something like this. As you can see the cat colour look really washed out and the spectrum doesn't look smooth at all.
Compare to this screen capture that I took (using ctrl-cmd-shift-4), you can see the cat colour is more "life" and the colour spectrum is smooth (I send the screenshot to my iPhone to make sure the screen capture have correct colours).
It's happen after I do an airplay mirroring using Apple TV that connected to HDMI to VGA adapter to my projector. I never do that before, as my apple tv usually connected to my TV.
This are what I already did after that thing happens: reset the NVRAM, try to reconfigure colour profile, restart my MBPr, and nothing happens. But when I try to mirroring either using airplay or direct hdmi connection, the display in other screen are perfectly normal while the display in my MBPr still washed out.
Any one can help?

My Macbook Pro Retina doesn't turn on but charger led works

I haven't used my mac for a month but it use to work perfectly fine. I tried to use it but it wouldn't turn on. When i plug the magsafe connecter the led goes orange. But when i press the power button it doesn't turn on. i tried smc reset using left shift, control and option (and power button) while charging and not charging but it doesn't work. Please help.

IF the battery was completely discharged, give it some time on the charger before trying to start up. The amber LED means it is charging, give it an hour or so before trying again.

Macbook Pro Retina will not connect to Panasonic E5 tv through HDMI anymore

When I originally purchased the MBP Retina, it connected to my Panasonic E5 tv without any issues. After an Apple update, now there's just blank black screens on both devices. I've tried all the resets I can think of. Both the MBP and tv are running the latest firmwires. This has been the issue since the end of September 2012.
I've tried the MBP on display models in the shop, and the same problem occured there.
Interestingly, the MBP does connect fine to older tv's (between 3 and 5 years) but not the new one. It also seemed to work on the Sony tv's
Has anyone else found this issue, and managed to resolve it?
Thanks
