MacBook Pro :: System Not Starting Up After Upgrading RAM
Dec 10, 2010
I upgraded my MacBook's ram tonight and now when I turn it on the Apple logo an spinning thing come up then after a bit the screen dims and it says, "you need to restart your computer. Hold down the power button untill it turns off, then press the power button again." I had two 1gb sticks and I put in a 2gb so I'll have three. I put the new one in the top slot but accidentally poped up the bottom one too. I've tryed about four times and put the original one in and get the same results. Could it be that I didn't push it in enough. If I can't get it to work tonight can I take it to the Apple store for them to see, and will I still be covered, I know they don't cover the new ram.
I'm going to buy the new Macbook Pro 13. It comes with 4Gb (2x2GB) but since I use lots of apps + VMWare Fusion I'd like to upgrade it to 6GB. I would replace 1x2Gb stick by a 1x4GB, having in total 6GB (1x2GB, 1x4GB). Do you think it's ok? Will it work? I found this memory on Newegg and it's pretty cheap ($115): [URL]
My macbook is so slow after upgrading to yosemite.
Here are the specs and the Etrecheck results. MacBook (13-inch, Mid 2010)processor2.4 GHz Intel Core 2 DuoMemory2 GB 1067 MHz DDR3 Graphics NVIDIA GeForce 320M 256 MB And also here is the Etrecheck results,  Problem description:My macbook is running very slow EtreCheck.
Bought my Macbook almost 3 years ago and it worked brilliantly but recently (after upgrading to Leopard?) I have become painfully familiar with the beach ball. Before it was blazing-fast. Now it always seems about two steps behind my brain. And that's really slow.
Did a quick search and couldn't find anything. My HD in my powerbook and full and I can't seem to start up my powerbook because the hard drive is so full. Does anyone know a way to get the computer started up so I can free up some space in my hard drive? I also have an external HD if that is of any help.
has all my art course work on. When pressing the power button there is no start up, screen stays black. There is a noise from the Disc Drive, when you put your ear close you can hear the Disc spinning, occasionally it starts to make a loader noise like its trying to spin to full speed maybe, but stops before it can. Green light can be seen from bottom, tried unplugging and waiting, tried pressing the cmd R-P keys down at start up. Also tried as suggested on the apple website to use a paper clip to manually eject the disc.
So, we have a bunch of computers that we need to install Mavericks on. After the second or third download, we decided to try to be smart and copy the installer to an external hard drive before installing. Now, when trying to install it on some of the remaining computers, it doesn't get very far and then comes up with an error that says something about required system files not being found. I will get the exact wording later when I go back to the lab. The installer already deleted itself from the other computer.Â
You must understand, downloading a >5GB file on a 25KBPS internet connection is agonizing, and these remaining computers need to get Mavericks on them soon.
I bought this in sept. of 08. The 24'' 2.8 ghz interl core 2 duoMy mac came with 2gig 800 hmz DDR2 SDRAM. what are good places to upgrade to 4 gigs. I have $200 in amazon gift cards, so that seem to be the front running. Do I need a certain brand or will any brand work as long as its ddr2 sdram?
I've had Last fm for a while, and whenever I plug in my iPhone or iPad, it will randomly start on its own, even after I force quit the app, it keeps doing it, and it drives me insane, it'll start up in the most inconvenient times, and I have to quit it at least three times before it finally stops starting itself. Is there a way to fix this, or do I just need to uninstall it and be done with last fm ?
"You need to restart your computer. Hold down the power button for several seconds or press the Restart button."
I get this message everytime I turn on my MacBook Air and cannot get past it.
When i turn the power off, it hang for quite a long time and this screen appears,
Macbook Air OS x 10.5.
Before this happened, i went on skype and firefox. But then it hanged, so i had to hold the power button to shut it down. I meant to restart it back but then i couldnt. This problem appears.
Just before it happened, i dont have any start up application. But before, they were adium, skype and transmission. And my 'HUAWEI mobile connect broadband internet' connect automatically. and i dont use time machine.
so I have read most of the start up problems, and mine is different. Whenever I shut down and try to start my computer again, I am not able to get my computer to turn back on. I hit the power button, and hear the computer humming, but not the typical hum-hum that usually occurs. My screen remains black with no activity. After 5 to 10 attempts at this, the computer starts up fine, and I have no problems with it running. I do not have this problem when I use the restart function, say after I download a software update. This problem is driving me nuts as I am afraid I can not shut off my computer!
After getting a message to upgrade airport, quick time , security and another two things that I do not remember I got a message that upgrade was not done and restart the MB. I did the restart but when the sign MAC OS X starting up shows it freezes there for ever. I tried disk utility from the disk but it tells me that disk is OK needs no repair. Tried single user mode , the same, tried to reistall OS after first disk blue emty screen.
Safe mode not opening. Is there a way to get back my data ? and make the system work again?
When i try to start my macbook pro 13" (early 2011) I get a black screen and it beeps three times. Based on internet research it appears to be a RAM problem. The closest store is 2 hours away and I don't want to send it away.Â

Yesterday my MBP suddenly froze while starting Google Sketch. Not just the program, but the entire computer. After a few seconds the screen started flashing like crazy. I waited a minute or so before I forced it to shut down.
After doing so I turned it back on and now it will not start up. I can turn it on, but then I will only see the turning wheel thing you always see. After a few minutes of turning wheel the wheel will freeze.
Talked to my local macstore and they told me to try and reinstall my entire system before sending it to a repair guy. And here is my problem.
It will not boot from a Cd or en usb with Lion on it. Not when holding "C", shift or any of the other keys down.
This morning I managed to boot from the system CD and erase my harddrive and start installation but, then it froze for an hour andIi had to shut it down again. Now I am back to not being able to boot from my system CD. Â Â
Is it a hardware error or what. My Mac is pretty old. It is the one just before the current MBP design came out. But have another computer, but I use this one a lot, so it is really frustrating that this should happen just before a possible new Mbp design.. Â
It seems like my MacBook Pro starts up pretty slow, about 20 to 30 seconds. I don't think this was the case before, I have the HD almost full but it has been like this for a while and just a few weeks back started to do this slow start behavior.

I recently upgraded the RAM and Hard Drive in my Macbook Pro 2012. I know that the first time it boots up it is suppose to boot up slower, but what about the times after. I upgraded the RAM to Corsair 8gb 1333 MHz DDR3 and the Hard Drive to the Seagate Momentus XT 500gb.
I've just updated my MacBook Pro to the 10.7.4 update, and after that update I couldnt boot my MacBook Pro anymore.
I doesnt pass the loading grey screen with the apple icon and spinning wheel. I tried to find solution on the internet, but unfortunately I couldnt find the fix yet.

I have a Mid 2007 MacBook (Core 2 Duo, 2.20 GHz, 2GB, OS X 10.6.8 Snow Leopard) and I am having a problem with iTunes. I have a fresh install and was going to sell the computer to a client when I realized that iTunes had a serious problem. Whenever I go to launch iTunes, I click on the dock icon. It bounces multiple times on the first attempt, but the program never launches by showing "iTunes" in the top menu. The little light never comes on beneath the icon either. Also note that on each attempt afterwards the icon only bounces once and then stops.
i have a year with a mackbook pro an it's work excelent. recently i leave my laptop doing a rip process, when i came back the screen was 'dirty' (a crazy carachteres forming down lines in the scrreen). I restart it then. but when it's staring, the apple sign apears 'dirty' again, and before that, a message in 4 idioms tell me that i must have restart my machine. I'been doing this several times... and the same happends again and again.
I have a G5 powerpc that is flashing a question mark. Whenever this has happened in my life with previous Macs i have pulled out my trusty install disc and fixed the problem, however i have lost the install disc.
I do have an intel MacBook Pro. Is there anyway i can wipe and install OSX on my PowerPC via my MacBook Pro without buying an OSX install disc?
Also, i had read that i could boot in safe mode by holding down shift but this has no effect. Does anyone know why?
I updated my 27" IMac memory up to 16 GB, so I was encouraged to do the same with my MacBook Pro after watching the video and instructions. However My MacBook Pro wouldn't start afterwards.

I have a MBP 15 inch 2.33GHZ running Snow leopard, ran silently out of battery for probably 24 hours, now fully recharged but doesn't boot up anymore. After switching on all I get is a light grey screen.
