MacBook Pro :: Apps On Core I7 Temporarily Freeze (randomly)?
Jul 15, 2010
I recently got a MBP (i7 2.66ghz, 8gbs ram, 7200rpm hard drive) and since I got it apps seem to temporarily (like for 10-15 seconds) freeze (only 1 at any time normally) and i'll get the spinning beach ball thing. Even if I only have say 1 app open (like safari) it'll hang up for 10 or so seconds randomly. It happens say maybe once or twice every hour (but having said that i've used it hours at once with a lot more than one application open and it hasn't done it) on various apps and I don't know why. Is it normal? I wouldn't think 1 app such as safari or itunes running should do that? It's not a problem(?) that bothers me really, I just want to know if something might be wrong? I've only had the notebook for a week so far and it's my first Mac.

I have had this problem for some time, on Leopard and on Snow Leopard (don't remember about Tiger), where my mac freezes for 2-5 seconds when my external drives are woken up. This happens often when I access the "file open" window, it will just sit there until the drive is started.

I've been having some strange occurances on my 2007 MacPro (2,1) where, in certain apps, the Beach Ball of Death will appear and the app will freeze or hang. I can be using the app for some time and perhaps do one thing, and the BBOD appears, the app hangs and the only way out is to Force Quit.It has even happened once or twice with Finder which forces a reboot.The app it tends to hang most in is Toast, especially when I go to burn a DVD. It will start the burn process, then just hang (the optical drive will start to spin up-- as if to start the burn-- then spin down and the BBOD appears. A Force Quit ensues.I can try to burn again and again but no luck, unless I restart the Mac Pro. Then it will work, no problem.But it has also hung using Mail, Final Cut Pro, Photoshop and especially Time Machine.I've gone as far as disconnecting Time Machine drive just to see if it is the culprit, as the majority of the initial hangs seemed to be associated with seeing the TM menu "clock" spinning, indicative of TM is doing a backup. Except the backup is taking forever and apps begin to BBOD as it spins.I can check the TM Buddy widget, which just says: "Starting standard backup Backing up to: /Volumes/TM Backups/ Backups. backupdb". Normally there's a lot more information than these couple of lines, especially if TM has been going a while.If I try to stop TM using the TM pulldown menu, the BBOD appears and it hangs, yet the clock icon continues to spin. And if I try to Force Quit, it hangs (and on one or two occasions, the Finder has even showed a BBOD and hung.And while I can move the cursor and click around the Desktop, there is no response.)If I click on an app in the Dock, then the icon freezes in the Dock at its Magnification position and I can do nothing to make it go back. Then I usually just do a reboot and all is well for a while.
I did add two extra Gigs of SDRAM about two weeks ago (from Crucial) and no problem.I did use Tech Tool Pro 5 and tested the Memory, which tested okay. Also, I can check Volume Structures with Tech Tool 5 on the main drive and it says everything is good. (I have two internal spare drives and one external firewire 1.5 TB G-RAID) I've used Disk Utility on the OS drive and checked Verify Disk on the Startup Drive and the others and after awhile, it says the hard drive(s) seem to be okay. I've even ran Apple Jack to see if cleaning things up would help but no dice.The only software I've added (on Monday and the problem started Monday) was a Seagate Diagnostic program to test some external USB Seagate GoFlex archive drives-- these are not always connected or mounted to the Mac Pro. When I started experiencing problems and it crashed or hung several times on Monday-- I trashed the Seagate Diagnostic program.The TM has also been shut down and unplugged as I tended to see more hangs and BBOD when it was in a backup process.The first TM backup of the day goes smoothly.An hour later, when it automatically begins another backup, the TM clock icon spins forever and trouble ensues as noted above)I'm wondering if it is my main Macintosh drive.It is a 250 GB drive, about 70% full and has worked fine until now.

How do you specify which core a program runs off of. If wanted to specify certain apps to run on a particular core.

Today I have had a ton of apps crash randomly in SL. Safari, Firefox, preview, mindmanager, pages have all crashed numerous times. Is it just me or are other people having reliability problems. I know apps crash but I have never really had a problem with it on other versions of osx...

As you can see in the attachment, the apps I'm running aren't that big of a deal for the most part. This is a 2007 version 8-core Mac Pro, 8 GB RAM. I'm curious what happens to make the apps open bog down the computer like this? Just leaving everything running for days at a time?

I see the numbers of everything from Core 2 Duo, to the slightly faster and cooler Core i3, to the supposedly faster core i5s and i7s. The benchmarks go up accordingly, but I found this does not always equate in a faster experience on most tasks.
Here's my experience so far on processor upgrade:
In one computer trade school re-certification class I am in, we are working with Windows Server 2003 on a Quad Xeon platform and it's incredibly slow.
But in a previous class we had the previous generation server edition on older Xeons, and while not fast, it was much better. On paper the newer multi-core Xeons should have made a difference, but could 2003 server software be that much more bloated than the previous Windows server edition that it would stall like that and make us wish we had the older setup?
I am going to try out the Adobe CS lab and put the new high end Dells to the test there and see if they work better than when we had an older CS version on older Xeon equipped Dells.
I don't know if this is something to do with Dell, or if Apple's increasing processor bumps/generations are going to similarly not make a difference in the speed things appear to go at, whether it's Adobe stuff, server stuff, or anything else that needs power.
I know somebody who plans on a Core 2 Duo, i5 or i7 MBP and I was wondering if the higher end processor is worth it in that case (iMovie being the main program of use).

My mid-2014 15" Macbook Pro randomly "loses" its retina display at the top menu (becomes pixel-y), where the battery, sound, and wifi logos are (on the top right side of the screen). A restart fixes the issue, but I want to know if this is an issue that can be fixed?

I temporarily lost all sound on my MacBook Pro. I hooked it up to my television and had good sound. Then I unplugged it from the TV and lost all sound. I couldn't get sound through the speakers on my computer, television, or iPod headphones. I went online and searched for similar problems. I was amazed at how many people had the same problem. Many of these people were forced to send their computers to Apple to have it fixed. I found this: [URL]

There's a lot of people wondering if the 13" MBPs would have been a lot better with a Core i3 processor, but everything has been just hangups over perceived old vs. new technology, and really the only thing the Core i3 adds is Hyper-Threading, but it doesn't have Turbo Boost, which helps the Core i5/i7s tremendously. Let's compare using Geekbench since it is cross-platform and one of the few available sources of info...
Core 2 Duo P8600 2.4GHz (~3362)
[URL]
vs.
Core i3 330m 2.13GHz (~3472)
[URL]
Core 2 Duo P8800 2.66GHz (~3700)
[URL]
vs.
Core i3 350m 2.26GHz (~3680)
[URL]
As you can see in both cases, the difference is pretty minimal indeed, and in single threaded applications, the C2D will easily outdo the Core i3 which lacks Turbo Boost and runs at lower clock rates.
And you get a 320M instead of Intel HD graphics with the new 13".
The Geekbench results from the old 15/17" to the new 15/17" are quite an order of magnitude better.
So unless people are expecting Core i5 processors in the 13", sticking to the C2D was actually a good decision, and given the differences between 2.4 and 2.53 isn't so large, one is far better buying the base 13" and then putting the money saved towards a good 7.2k HDD or SSD.
Note - I took averages of the 32-bit numbers and added them.
Note 2 - The C2D Pxxxx are 25W TDP processors, which are more efficient than the Core i3 which are 35W TDP processors. Less heat, better battery life from C2Ds.

I've been debating whether or not to upgrade my 3 year old 15" Macbook Pro that has a 2.2Ghz Core 2 Duo (Santa Rosa) to the new 13" 2.4Ghz Macbook Pro. FYI... My current system also has 4GB of RAM. Since both systems are Core 2 Duo, what kind of speed bump am I going to see? Would this be a substantial upgrade?

As much as I trust him, I have a suspicion he might vandalise my facebook or bid on something on ebay, since firefox remembers my passwords. So, if I drag firefox out of applications and onto a pendrive, will i be able to stop it working and then drag it back on the next day? (I know it would work with most apps, but I don't know where firefox keeps passwords and cookies etc)

The ivy bridge processors are coming out soon (or may already be out). I have heard that macbook pro 13" models might be able to use the new processers due to their lower energy useage. I presume that I will be able to take my mac to an apple store and have it installed. Is this information true?

Just in case Apple surprise us with a Sandybridge Quad core, and even if they don't I was wondering the following.
1 ) During sustained use in 3D gaming does a Quadcore with lower clock speeds beat a dual core with higher clock speeds.
2) Can the quoted turbo speeds be achieved in sustained use (ie 3D gaming where maximal load can be applied for a couple of hours).

I noticed my trackpad started acting funky last night. It won't happen right away when I turn my MBP on, but usually after some time (depends). First thing that happens: it responds slowly; it will move the pointer less than it would normally and it will judder along. Pressing harder doesn't help and sometimes two-finger scrolling won't work one way, or sometimes using my other finger will work better. After some more time, it will stop responding entirely or get unusably slow. I noticed restarting fixes it (temporarily; once again, it depends). Just before posting this, it happened until it didn't want to work at all, and I let it sit for a few minutes, came back, and it worked fine. Ten or so minutes later, its still working (no restart). It's troubling and I'll probably take it to an Apple Store to have it checked out, but I won't have time to do that for some time, so I'd like to see if this is possibly something well-known or fixable.
I thought it might be dirty, but I cleaned it, well, a few times, and still nothing. My hands are clean, too. I thought it might be something I "spilled" onto my keyboard a few days earlier; it wasn't anything watery, it was a rather thick consistency. I hope that isn't it, as I cleaned it quick and well, and it wasn't on the trackpad, and the keyboard works perfectly. The only thing I was doing when it first happened was video chatting via MSN (MSN gets my Mac hot, and I was worried it was the heat that did something, but IDK for sure). I only started using MSN about a week ago, and it gets my Mac really heated each time I use it. I did some searching on Google about this, but nothing quite like my situation. I haven't looked at everything, but, nothing yet.

Although i'm hardly impressed by the prices and specs of these 'new' machines I need one so I'm buying!
Just need to know before I make the plunge. Is the i7 variant with the extra GPU ram really worth it? I would use the extra power in my work but I honestly need to know if I'd notice any difference as for a few seconds less waiting it would hardly justify the price.

I wanted to know if I can replace the upper case of a Core Duo white macbook with that of a Core 2 Duo black macbook? The white one has the distinctive yellowing of the rev A macbooks, so i'd like to make it better whilst making a black/white frankenMac.
If not, can I at least replace the airport card?

I am looking to purchase my first Macbook Pro. I am having a difficult time deciding between a $1749 17" from Amazon that is the older 2.8Ghz Core 2 Duo and the $2298 17" (w/ student discount and tax... have to include tax) from Apple that is the newest model. The price difference is $549.
Some things I'm curious about:
1. Intel HD card? Does it really cause that much lag? How is it compared to the nVidia 9400m? I don't mean benchmarks, I mean real life performance.
2. Battery life? Is the battery life in the newest model much better than previous gen?
3. Heat? Is there a difference in heat production between them?
I don't care about gaming, so the 512 300m vs. 512 9600m is no concern.
Does the newest 17" justify the $549 price difference? Are there any other things that I should know between the two?

is it even possible to upgrade an old dual core powermac g5 to a quad core or even an 8 core.
I have a dual core one and i really need to upgrade to a quad or even 8 but it is so expensive to buy a whole brand new one and i was wondering if there was a way to just get a new processor and more ram or what not.

So the older Mac Pro's from 2008 have 2 2.8ghz Quad Core Intel Xeon processors, without hyperthreading, for a total of 8 cores, and the top of the line iMac has a Quar Core i7 2,8ghz with hyperthreading for a total of 8 (virtual) cores.
With the ghz being the same but less "real" cores, but probably newer CPU architecture, which CPU will actually be faster?
