MacBook Pro :: WiFi Cuts Out Sporadically And Frequently
Jun 23, 2012
in the last week or so I've begun having a problem with the WiFi connection on my MBP. While using the Internet, web pages will no longer load, my mail client can't connect to the mail server, etc.When I use the terminal to ping Google or any other site, I get the message that the server can't be found.In the menu bar, the WiFi icon indicates a strong connection, but when I open Network Preferences, it says that WiFi is off.When I click, "Turn WiFi on," the menu bar icon goes to the empty fan icon but WiFi refuses to turn back on again.The only thing that I've found to work is to restart, and once or twice now that hasn't worked either.
One other thing I noticed was that this last week Network Preferences had identified my fitbit tracker USB syncing dongle as a network device and had added it to the list of devices on the left side of the preferences pane.This happened after I had already begun to have problems, and after I deleted the syncing dongle from the list, WiFi came back up again with no problem.This is a MBP with a 2.7 GHz i7, eight GB of RAM, running 10.7.4.Can you offer any solutions or suggestions for further troubleshooting?

MacBook Pro, bought in April of 2007. I've had this thing for almost three years now and I love it. It's my baby and has been with me through alot. Anyways, I've never had a problem with it before until now. Actually I take that back, the battery went ka-put about a year or so ago when it was under warranty. Regardless, here's the problem: The LED doesn't shine anymore. It's really dim. The battery does not charge at all, it's stuck at 0%, so right now I'm stuck with a really cool desktop.
When I play music from my computer on my stereo, the line out feed has a lot of static interference, like theres a ground or something in the metal casing of the computer. The computer randomly shuts down. I've come to notice it normally does this when it is under "too much" stress. (ie: too many windows or applications open) I use quotations because I bought it w the 3gb upgrade and it never has problems w RAM, so for it to be shutting down the computer when only 4 safari windows or tabs are open is bull..

My MBP 13" (summer 2009) has been getting slower and slower for a while. Finally yesterday it was just hanging on the spinning rainbow and completely unresponsive. I had to hold down the power button to restart, but even then it was frozen, no matter how many times I restarted. I had everything pretty much backed up, so I deleted my HD and did a clean reinstall of Lion.
Even that had hiccups: at first I was getting the error message that the HD couldn't be deleted because the disk couldn't be unmounted. Finally when booting from a Lion DVD I was able to delete and clean reinstall. All seemed well last night but today I am still noticing some problems. There is a few seconds delay when opening any new folder in Finder, opening a program from the Dock, or clicking on a menu item.
Sometimes the cursor gets frozen on an arrow or other special cursor, after mousing over a link or seemingly for no reason at all. When typing, I'm getting sporadic delays: three times while typing this message, the computer froze up for about 5 seconds, and then the text finally appeared. I'm also seeing similar delays in scrolling.
Sometimes scrolling works, sometimes I need to wait a few seconds for a webpage to become responsive. This is alarming to me considering that there is almost nothing installed on the computer except Lion and a few light programs (Evernote, OpenOffice). I haven't put anything back on the computer from the backup since the clean reinstall.

My MacBook Pro 13" i7 2012 model keeps sporadically freezing. I can see the screen, but can't do anything, just hear a stuttering sound, for example if I'm listening to a song it repeats a tiny segment of the song non-stop. When trying to use the webcam on Tinychat it also periodically froze and stuttered.Â

my macbook pro has started to just cut out randomly. I have had this with an expanding battery and haven't had the money to replace it yet, but I don't know if this is part of the issue. When my computer cuts out, it is as though the power cable has been pulled out and the whole system just shuts off in an instant. I know that the power cable has definitely not come out, though.

I sent in a question, but I thought I would also post a thread in case anyone else might have some helpful suggestions.
I have an iBook G4, Tiger edition 10.4.11, 1.07 GHz, 768 MB DDR SDRAM.
My system sporadically freezes. Whenever it is moved (i.e. resituated on my lap, or from my lap to the table). Or if I leave it unattended for a period of time (i.e. downloading something, and walk away, by the time I come back it's froze if I am not constantly DOING something). Or if I try to access 3 or 4 applications at a single time.
Sometimes the freeze is a complete system freeze where nothing works or moves. Sometimes everything but the mouse freezes and I can still move the black arrow around. Sometimes it freezes and the little beach ball just keeps spinning, but is still mobile.
Sometimes after it freezes it will not restart. Instead it goes to a screen where it is all white with black flashing horizontal lines.
Sometimes a screen will pop up and say simply "You need to restart your computer. Please hold down the power key."
The only thing that I've found that fixes the screen is to take out the battery for 5-10 seconds and then it restarts immediately and perfectly.
I've done my "google" research and found that the early G4's (which mine is) have issues with the logic board and my Mac showed similar symptom's. It also said the "clamp" method temporarily fixes the problem. I tried this and it did nothing but readjust the black flashing lines. It did not fix the problem.
I've tried completely reformatting my hard drive. Starting from scratch. I installed an additional 512 MB of RAM on top of the 256 built-in. I ran Disk Utility to verify and repair permissions. I installed SMART reporter, and it says that my hard drive is fine. I ran ClamXav before reformatting my drive and it found nothing. I can't run it now, it freezes before it's finished every time

I'm really interested in MB Air but it's little bit expensive toy for me. Do you think there are any chances for a price cut (after releasing the second generation)?

the display's started cutting off unexpectedly. It started a few months ago with random restarts, which I thought were caused by a bad hard drive, but it turns out permissions errors, stacked up over the years, really can bork your computer. I replaced the hard drive (didn't mind opening her up, since she's well out of warranty), but the problem kept occuring - only with the screen going dark randomly. I thought the new hard drive was dying, too. But here's how it's been going down lately. About twice a day, the screen will go black. Not just the backlight; it's as though the display has been turned off. I can't wake it from the display sleep, but it's not for lack of hitting the space bar repeatedly. Keyboard backlight stays on for a second, and then goes dark, at which point, I'll force a shutdown and try to restart. All of which is messing with my data; I've been doing a permissions repair pretty much daily now, and there's loads of 'em to repair. I noticed today, when it happened earlier, that my hard drive is still spinning, and USB peripherals retain their power. So what is causing my display to cut out like this, and how do I keep it from happening again (at least this frequently) until I can afford a new MacBook?Â

The audio on my macbook pro cuts out after a few minutes. It sounds like all the low end is removed. I still hear audio but it is MUCH lower and sounds filtered. I can barely hear it maxed out. Nothing attached (no external drives, no speakers, etc) and it's only a few days old.

I've connected my Macbook to my Samsung TV via HDMI and it works great!
I've been using the TV for it's speakers and screensaver so I'd like to be able to put on iTunes and have my slideshow play on the TV while I have guests over.
It works great, but if I don't touch the macbook for 20 minutes, the signal to the TV cuts out. The Macbook isn't going to sleep, because I've adjusted those settings accordingly. I feel like the TV is stopping the connection for some reason. As soon as I touch my macbook, it resumes playing and everything.

I am trying to repair a macbook pro for a friend, I think it's the logic board, but I wanted to check with you all before I go buy one. When the battery is fully charged, I press the power button, I hear the hard drive spin for about 5 seconds then stop. The superdrive on it is broken so I can't try the restore disk. I ordered Pram, I am going to replace that. I tried two different hard drives and I know they are both good, I tried them in the macbook and through a usb port, and the same thing happened both times.

I have a fairly new 17" Unibody MacBook Pro, and recently my AirPort signal cuts off after about 30 minutes. I could just be on Facebook, and I will loose the signal after 30 minutes, and then I got to reselect my network. It becomes very annoying if when I try uploading videos to YouTube, having to start uploading all over about 3 times. I took it to the Genius Bar on Saturday, and they couldn't diagnose the problem, and they said they have to send it out to depot, but i can't afford being without my machine till June. I've tried restoring the default settings on my AirPort base station, but that didn't effect the problem. Could there be a problem with the AirPort card in my machine?

I have an old Dual 2.5 GHz PowerPC G5 (aluminum tower). When it boots up, I get a message that the Date & Time are no longer correct. I go into date and time settings and reset them, however when I shot down and reboot later, the time has been reset to June 1969 or some similar date. Also, when the computer shuts down, it cannot be rebooted immediately. If I try to reboot it, I hear the fans start up and drives start spinning, but then they all seem to power down (a red light can still be visible inside. If I shut it down and wait 15 minutes, it will boot up fine, however the date/time has reset to 1969. Â
I have done the obvious things like replacing the clock battery and resetting the pram and smu, but still no joy. I suspect a hardware fault of some kind, but don't know what to try next.

I own a 15 inch mid-2010 macbook pro and have Windows installed via bootcamp. Because of this, I often shut down and reboot the computer into the other partition. I would say I switch between Windows and Mac OS X about six times a day.
Since I reboot often, I was just wondering if doing this does any damage to the hard drive or other hardware.

My MBA has the clicking and it is quite annoying but when I am using Windows through Bootcamp, the clicking occurs less frequently and is not as noticeable. Does XP access the hdd differently than OS X.

When I got my MacBook a few weeks back it had a faulty disc drive and subsequently got replaced to the MacBook I have now. Getting back to the point on both this macbook and the first macbook I had it had a strange issue, where sometimes the trackpad cursor would freeze for a few seconds even though I'm moving my finger over the trackpad still. It would occur more often when I have my leftside-finger on the bottom left of the corner and tracking with the my rightside-finger as you would a usual notebook...it happens quite frequently.

My mom and I have the exact same Macbook Pros (10.6.5) but while mine works perfectly, her browsers crash all the time. She's tried, Safari, Firefox and Chrome. We are connected to the same internet so we know it's not a problem with that.

My Macbook Pro has been freezing frequently for about 30-45 seconds at a time. The screen will freeze, sound will stop, but the color wheel will spin and i can move it around with the trackpad. I don't know what is causing this/any possible fixes to my problem. I purchased the macbook pro in mid 2009 and it has OS X lion 10.7.3 installed on it.

Odd stufff, I have a 500 gig Lacie ext HD that my user uses on her Vista machine...
I am setting up a replacement for the Vi$ta machine, which is a 24 inch imac.
I plugged in the ext HD and nothing happened after I powered on the ext HD.
I checked disk utility and it showed up but as a 2TB size ext HD...
I unplugged the Lacie and plugged it back in and all the info showed up correctly.
But ALL the buttons under "First Aid" are greyed out so I cant verify permissions, disk, or repair disk or permissions.

This happens once or twice a day and is very annoying. I will be browsing on Firefox, for instance, and I will scroll down and for whatever reason, after that any click will be interpreted as a right click, bringing up the contextual menu. It does not happen when I'm using a wireless trackpad; only with the trackpad on the computer itself. It will fix itself after a few minutes, again with no reason.

I purchased the new 13-inch Macbook pro on the day of its launch and since the first 30 minutes of use it has constantly frozen intermidiatly for apperently no reason. I've tried re-installing the OS, taking it to the genius bar(They said everything looks ok and on the repair sheet it said "UNIT IS RFB"), and resetting the SMC. I checked the kernel log and it has a tendency to throw this: 7/4/12 12:02:42.000 AM kernel: Previous Shutdown Cause: 3. Read up on this and apperently it has to do with overheating issues, but this doesn't make sense condsidering it can happen even when just doing textbased web searching(I do not have adobe flash installed). I tried ressetting the SMC, changed nothing. Some days it may only happen once or twice, but sometimes it happens so frequently that the computer is barely usable. Apperently I am not the only one having this problem, some people are reporting the same thing but claiming it to be a problem with the Intel 4000 graphics card. The model is the baseline 13-inch Macbook pro running OSX 10.7.4.

Recently my MBP retina late 2012 started crashing with the screen going all black leaving the keyboard lights on. I had to force it to restart. After a couple of attempts I could finally access the computer for about 10 min before it crashed again, during which i could see the logs. As of know it has been on for 1 hour without any issues but when I run some more hardware-intense programs it crashes. Since i bought the computer from a private person without insurance im not entitled to the 3 year warranty.Â
Im getting these errors:

I'm on a boat in Fiji, using a Vodafone wireless dongle, and keep losing my connection. My vodafone software and my apple network software show I'm still connected, but suddenly I can't get into another page, or if I'm downloading a software update, I get a message that I have a timeout error. I then disconnect my connection and re-connect and then things start happening again. However, I have not been able to stay active long enough to download my apple software updates which is really frustrating. It seems to happen more often when I'm downloading something sizeable, like a video or software update, but happens other times as well. I'm a mac novice, (bought this, my first mac about 10 months ago) and not terribly computer savvy to begin with. Looking through this forum, I'm confused by much of what I read, but I'm beginning to think this problem may be beyond my capacity to solve.

my MacBook pro display that there are frequently horizontal grey lines going across my screen. I've noticed it mostly when the display color should be grey or white, but that's not always the case. It occurs mostly in my Google search bar using Firefox, and also occurs heavily on Facebook in the comments/reply section of a post. Outside of the browser I've also seen it when looking through some personal photos, especially of the sky, the lines will seem to sort of outline different contrasts in white or light tones, kind of like the Magic Wand tool would do in Photoshop. The lines do flicker and change when scrolling.I attempted to snap a photo with my iPhone the best I could.Â

I re-installed my Music according to Apple's instructions, but that didn't resolve the problem. Some songs are getting cut off at around the 3:00 mark, and when they do, iTunes doesn't proceed to the next song. I'm operating Mac OS X Lion 10.7.4 on a brand new iMac and have never had this problem before.
