MacBook Pro :: MBP 15" Latest Model Spontaneous Reboots?
Jul 1, 2009
Last week I bought a new model 15" MBP which spontaneous reboots every hour or so. Yesterday I returned it and received a new one (including new power supply etc). This one however does the same. Yesterday evening I started a Time Machine restore which was stopped in the middle because of a spontaneous reboot.
I resetted everything (SMC, PRAM, etc.) and tried again. Still reboots after apprx an hour. It doesn't run too hot (67C, 2100RPM). What can be wrong?

I am trying to figure out for certain, does the newest 13" MacBook Pro model with Nvidia 320M graphics support OpenCL out of the box? I would guess that it does, but I haven't found a clear answer for it anywhere. The 9400M on the previous model is mentioned as OpenCL-supported.

I just received the 13" MBA last week, and it's crashed nearly every day since then (one kernel panic with that black dialogue window telling me I need to reboot; all the other times it just spontaneously freezes out of nowhere and my cursor / keyboard doesn't jog a response). I called Apple this morning and the guy said he knew nothing about it, took me through some tests, and said hopefully it won't happen again. It just did.

I am trying to decide whether to get the 2010 model or the cheaper 2009 model. These are the differences that I've found so far for the base model. For arguments sake, let's say they both have 4gb ram (most people selling them have upgraded to 4gb)
2010: 2.4ghz, longer battery, nvidia 320m
2009: 2.26ghz, (slightly) shorter battery, nvidia 9400m
Having a slightly slower cpu, less battery life (about 7 hours rather than 9) and a slightly weaker gpu don't bother me so much, as I will be mostly using the macbook pro for internet surfing and writing word documents
My question is, are there any other differences? (that would make me go for the 2010 rather than the 2009 model) - maybe differences in the display? shape? something else?

i am contemplating buying a late 2008 mbp air i found for $800 on CL. it has the 1.86 ghz 2gig ram and an 128 gb ssd. would that be comparable to the new 2010 version? i know the new one will edge it out, but by how much? i do a lot of art using flash, illustrator, and ps but just want to use this machine occasionally when i travel, ill have another machine for the heavy lifting if needed be. is that a good deal? or should i just wait and get the 2010 version which is double that?

PC World (in the UK) are selling the old 2.66GHz 15" model for �1,149 (rather than �1,499 for the new model).
The differences between it and the new model are summarised below (as I understand them)
Battery: Old: 5hr, New:7hr non-swappable
Display: New: Better colour gamut (apparently?)
Processor: Old: 6MB cache, New: 3MB cache
Card bay: Old: Express34, New: SD
Of the above only the battery life is of any relevance to me (unless the display quality is really that different?). The SD card would be marginally more useful than the Express card.

I've been contemplating recently (as most mac users do) about switching my 2 year old MBP (2.2 ghz, 2gb ram, 8600m) to the new MBP (15" 2.8, newer gfx, touchpad and a few minor details).
I've been eying the ebay prices for some time and my particular model (with charger, snow leopard, original accessories but w/o box) is valued at about 700gbp. Perhaps people might disagree with me here - how much is it really worth ?
My main point / question is really at what point should I ditch the existing MBP in favor of the new mbp - does it really offer me that much of a benefit at this time to upgrade? I'd sure like the new graphics card in there (is it really that much better?) but I'm not sure there's a significant enough difference there.
On the other hand if I wait much longer the MBP will become pretty devalued and not get me much back for the new and improved MBP - maybe apple's going to improve them soon anyway?

I am about to buy a computer and just been doing some research. When I went to best buy and ran a geekbench score on the imac it was like around 5800.
A seller on ebay who is selling a Mac Pro 3.0 ghz just ran the score and posted the results of 6214
[URL]
Based off of this score alone wouldn't it mean that the 2007 Mac Pro is faster than the newer 2010 imac

I have an old black MB 2.16 ghz C2D. At times, it locks up and randomly reboots. Sometimes, it gets crazy and reboots again after its done booting up. Sometimes, I get this gray screen that says I have to hold the power button as well. I don't really notice the laptop getting warm at all or the fans turning on that much. I just reinstalled the entire OS and Snow Leopard. I just got a new MBP, so I haven't really been using that one as much (or at all). So, it's hard to say if that fixed it. My applecare runs out on 5/29/2010. And if it's a hardware problem, I'd like to get it fixed prior to my warranty expiring.

i have been having some problems with a JMicron 0x2329 usb enclosure, on a new iMac. Sometimes it suddenly unmounts, giving the "improper ejection" warning. To which i usually reply out loud- "No i'm pretty sure i didn't- you did." It doesn't make any difference, it refuses to take responsibility for it's actions.
I guess the first thing is... is it the computer, the enclosure, or both? It's not the cable.It's not the directory, diskwarrior gave it the green light, and i optimized it anyway.disk utility finds no problemsInside is a hitachi 1TB, hfs journaled drive1 partitionI've stopped and started journalingI've turned off ownership.It's been plugged into the computer, and a powered hub.It's intermittent (it appears that way anyway) the computer is as follows:
Model Name: iMac Model Identifier: iMac12,2 Processor Name: Intel Core i5 Processor Speed: 2.7 GHz Number of Processors: 1 Total Number of Cores: 4 L2 Cache (per Core): 256 KB L3 Cache: 6 MB Memory: 4 GB Boot ROM

I've been digging around for a couple weeks now for information on what may be happening to my MBP. I've tried numerous solutions, but don't seem to be able to get the computer to STAY ON. Here's my story:
A couple weeks ago, my room mate was using the computer. She closed it to put it to sleep, and left it on my bed. When I went to turn it on, the screen was completely black and the indicator light on the open button was a steady grey. The computer was so hot it was painful to the touch. I unplugged it, hard powered it off, and let it sit, thinking it was an overheating issue.
Since then, the damn thing won't stay on. Initially, it would intermittently just shut off. When that happened, sometimes I could boot it back up, and other times it would sound like something was whirring in the background, but the screen stayed black and the indicator light stayed solid grey. I installed SMCFan and istat to monitor/control the temp and fans.
I noticed somewhere along the way that there seemed to be some connection between episodes of shutting down and the power cord (as in, if it was jostled, the computer shut off)(I should note that my battery is at about 15% health with a full charge). Then, that power cord died (no green/amber indicator light and no connection detected). So I bought a new cable, and set about trying to fix the problem again.
Next phase, it seemed that if I moved the computer, it shut down. So I did some of the recommended fixes. I deleted the power management plist, I changed the settings to never put the computer or the display to sleep, and I turned off the quick-motion sensor that stops the hard drive. I also reset the SMC settings.
This seemed to improve the situation a little bit, insofar as now instead of getting a shut down, I am now getting complete reboots that only *sometimes* lead to the blank screen and steady grey indicator light. This does happen more frequently if I move the computer, but it can also happen if I simply leave it to run. In fact, if I send the computer into sleep-mode, and close the lid, I'm practically guaranteed a reboot.
So, then I reset the PRAM and did the hard-reboot (ctrl+opt+power) and reset the PRAM again. I am currently running Rember to test the RAM, but I'm not sure what to look out for when it finishes, or what I should do about it.

First couple of times this has taken place I thought I was making a mistake or possible a power setting somewhere but finally yesterday I realised after checking all settings that my MacBook is actually rebooting and closing all apps for some reason.
Typically occurs when left alone for a hour - not every time - but at least 5 times so far this month. Has anyone else experienced this or do I just have a defect problem with the hardware? What can I do to troubleshoot this? Are there any system logs in this OS that would give me some clues if this is applicaton or hardware related?

My new Macbook Air (bought one mounth ago) reboots automaticaly. It happens randomly, usually when I'm using Safari or Skype. It shuts down without any warning and log-out process, and it's keyboard keeps unresponsive about 1-2 minutes and then boots up automatically. I'm not using any "Disk cleaning app". I have reinstalled OS but unexpected reboots keeps happening.

I just bought my new 2012 macbook pro a couple weeks ago, and so far it has crashed and rebooted by itself four times. Three of those four times, I had only been running a couple programs, such as Chrome and Mail, while all others were closed. the entire computer will freeze for about 6-7 seconds (no response to mouse movement/keyboard) and then shut down and reboot.
Is this a bug with OS X Lion? or the new macbook Pro? or my macbook pro specifically indicating there's some sort of defect?

Whenever my Macbook powers down to 0 battery life and reboots from a new charge, I loose all my software settings, including browser cache, adobe settings etc. It's really annoying. I have a brand new MacBook Pro 15" 2.2Ghz i7.I'm running OSX 10.6.8 on it (I reverted because I didn't like Lion).

I have a mid-2010 Macbook Pro with a 2.53 GHz Core i5 processor and 8 GB of RAM, running OS X 10.10.1. For the last few weeks, at apparently-random intervals, the machine has been rebooting while I've been using it. I can't tie this to anything in particular that I'm doing. It may go a couple of days before a restart, or it could be like today, where it's happened five times in the last four hours. I've tried resetting the PRAM and the SMC without apparent effect.
When the reboot happens, the system first freezes for roughly 30 seconds--the mouse pointer won't move, it's unresponsive to keyboard input, etc. The system then appears to power down--the screen and external monitor go dark, fans stop, keyboard backlight goes out. A few seconds later, it powers up, gives the boot chime, and goes through the normal boot sequence. At no point does it give the "your computer was restarted because of a problem" message, and I don't see anything in the Console app that looks like a kernel panic.
About two years ago, the logic board was replaced to address a somewhat-similar issue--the system had been freezing and could only be recovered by a hard power off (holding down the power button for several seconds).
I'm not sure where to start looking for the cause of this problem, since I can't figure out anything in common with the circumstances surrounding the reboots.

I need the thoughts and advice from your seasoned Mac people - I have 2 MBP's - 1 15" aluminum, one last years model 17" Unibody (with Black around screen). The 15 has run great since day one. The 17" was ok, but now is locking up and causing me to reboot, fans seem to run on high all the time, and it is very slow to react while using the OS, it gets worse until it locks up. I have upgrade to Snow Leopard thinking that that might fix it, but it has not.
When I got it, I restored from the back up of my 15" using carbon copy cloner. I only imported users and data such as pictures and music. Do you guys think that this is a hardware issue or a or should I back all my stuff up and then blow everything away and reinstall from the ground up with a fresh SL install?
When I called apple they tried to sell me apple care and told me that it was out of the full warranty and if I send it I would to pay for what was not under warranty. SO I am hoping that someone has seen this and has a fix that I can do without having to take it in.

I am trying to decide which of these two 27 inch imacs I should buy:
27 inch 3.06 core 2 duo model
27 inch 3.2 I3 model
Is the 27 inch 3.2 ghz I3 model a better value in terms of increased computer and graphics performance and is it better to get the 2nd generation model because of prior issues (i.e. yellow tinge)?

I recently updated to snow and since then have had problems turning off mac. I've reset pram, tried unplugging externals, tried logging out, then shutting down, but every time I hit apple-shutdown it goes black, and reboots. I can put it the screen to sleep with hot corners, but never turns off unless I manually hold down power.

Is there an event log or something? I leave it on all the time, good airflow around it and it's on a ups. It didn't crash for the first year but now it's almost daily. I use this one for the house itunes server so it's extra frustrating. Any ideas on what to look for? I've made no mods at all, even the RAM was from apple (when I bought it).

Do you guys recall when one of the advantages of Mac OS X over Windows was that it required fewer reboots after software updates and installs?
I recall it being one of the selling points in maybe a few of their commercials and advertisements, way back when, along with "quicker boot times".
It seems that -- nowadays -- I'm required to reboot OS X almost every time their is a software update for the OS or value-added software, while my Windows box seems like it goes months between required reboots after Microsoft software/OS updates.

Mac Mini was running really slow. So we reformatted the hard drive and restored the computer using our restore disk and our Time Machine backup. After restoring our system, when it reboots, it reboots to a blue screen. It sits there and sits there.
