Drastic slowdown on Macbook Pro quad core after the mighty Yosemite upgrade.

Is anyone @ Apple recognizing this issue after the Yosemite upgrade.. my laptop went from blazing fast webpage and software use to a slow turtle.. my pentium celeron is running faster than my current Apple laptop.. There should be a warning saying your PC will turn back 20 years by choosing this upgrade . everything is slow.. it take close to 30 seconds or more to boot up.. come on now I have a SSD.. did not have a problem with Maverick.. Youtube will buffer with 16gb memory.. the wife cuts of random.. all these issues after Yosemite.. what the deal Apple is there a fix or I need to go buy Maverick from the Apple store and re-install? I done have a back up.. I'll re-install and loose my data , no big deal.. but I refuse to run Yosemite with the power less than celeron laptop..
Here are my specs:

Why is my macbook pro running slow after os x yosemite upgrade

Why is my macbook pro running so slow after os x yosemite upgrade

Please describe the problem in as much relevant detail as possible. The better your description, the better the chance of a solution.
For example, if the computer is slow, which specific actions are slow? Is it slow all the time, or only sometimes? What other changes did you make, if any, just before it became slow? Have you seen any alerts or error messages? Have you done anything to try to fix it? Most importantly, do you have a current backup of all data? If the answer to the last question is "no," back up now. Ask if you need guidance. Do nothing else until you have a backup.

Can Tiger (OSX 10.4) run on a Macbook Pro quad core i7

I have a Macbook Pro 2.2 GHz quad core i7. I would like to have three partitions one for OSX 10.6, one for OXS 10.4 to run some older software and one for Windows 7. I have these 3 partitions setup and OSX 10.6 and Windows 7 installed and working properly. I now would like to install OSX 10.4 to the 3rd partition but can not boot to the installation disk. I tried holding down the C key, I tried a different copy of the disk which will boot my older mac so the disk is OK. Can this be done or is OSX 10.4 to old to run on the i7. Is there another way I can install other then from the CD.

Apple cautions not to install an OS earlier that what the Mac came with...
http://support.apple.com/kb/HT2186
http://support.apple.com/kb/HT2597
In practice it really matters if there were Hardware changes since that model/line came with 10.4, the earliest MBP i7 I see, came with 10.6.3, so I doubt 10.4 or 10.5 will run on it.
Is there another way I can install other then from the CD.
If you want to try it, you'd need an older Mac that could boot from that Install Disc & your new MBP in Target mode.

I have a iphone 4S, Macbook Pro(Quad Core) 2HP pc's, can my AIRPORT EXTREME STATION work w/o a problem w/both my pc's?

Can anybody help and answer my questions please?!?!?! i am ready to set up my Airport Extreme Base station, and i have a feeling that my iphone 4S, and Macbook pro will not have a problem connecting WiFi to my base station, but in my other Two rooms i have two HP pc's. One for each room, and i have a feeling it's not going to be easy to connect wifi to my extreme base station as easy as my Apple products. B4 i set up base station, is there something i need to know to connect my HP's w/o a problem?

I would recommend that you start by having your 802.11n AirPort Extreme Base Station (AEBSn) broadcast a clean" Wi-Fi network. By clean I mean do not enable wireless security, MAC address filtering, or use a hidden Network Name (SSID).
Once you verified that all of your wireless clients have no issues connecting, then proceed to enable wireless security. I would strongly recommend using WPA2 Personal as your Wireless Security type choice.

MacBook Pro Battery bulging after 10.6.8 upgrade

I have a MacBook Pro Core Duo 17-inch: 2.16GHz (MA092LL/A), purchased in May 2006. It has been a superb performer. I ran Tiger (10.4.11) on the machine until recently, when I upgraded to Snow Leopard (10.6.8). I usually run the machine on the power supply, but the battery has never had any problems. I had the full 3-year AppleCare warranty on the machine, but obviously that has expired.
Today I noticed that the battery (A1189) was bulging. I hadn't used the machine for several days. I've probably used it for a total of 4 hours since I installed 10.6.8...and all of that usage was with the power supply connected.
I removed the battery and inspected it. The cover plate (with the battery check switch and LEDs) was separating from the body, obviously being pushed up by expanding innards. All 5 LEDs lit up when I pressed the battery check switch, so I replaced the battery and booted the machine (power supply attached). The battery indicator in the menu bar showed that the battery had 100% charge. I usually run the machine with an external Apple keyboard and mouse. Within a few minutes I was unable to use the mouse. The pressure from the expanding battery was locking the trackpad button and disabling all mouse click functions.
I released the battery locks; it wasn't easy due to the pressure caused by the bulging battery. That relieved the pressure on the trackpad, after which the mouse (and trackpad button) worked normally.
Unfortunately, I can't check the battery info in System Profiler; installing the battery locks the trackpad button and disables all mouse functions. However, my usage of the machine has been light, and I've mostly run it with the power supply attached. I have deliberately run the battery down to zero to calibrate it a few times per Apple's instructions, but since the vast majority of my usage has been on the power supply, battery performance has never been an issue. In the few dozen times when I've run the machine on battery power, it worked fine. I would estimate that the battery has used significantly less than half of its available charge cycles. It's obviously still holding a charge.
I've seen a number of posts here in Apple Discussions implying that Snow Leopard 10.6.8 might be causing some problems with MacBook Pro batteries. All my software is up to date. I understand that batteries don't last forever, but the fact that the battery is self-destructing within a few usage hours after I upgraded to 10.6.8 causes me to suspect that this isn't just a battery problem. I don't want to replace the battery and have it self-destruct again if there's a system power management problem.
Can anyone provide any suggestions or information on this issue?
Thanks!

stevekn:
After the same thing happened to me, I spent a great deal of time researching this issue. When I wrote the original post in this thread, I was asking whether there was a causal link between my upgrade to OS X 10.6.8 and the bulging battery problem. From the standpoint of the system itself and its ability to manage the battery functions, I'm now convinced that no such problem exists. Similarly, I'm convinced that there is no intrinsic defect in the battery itself...well, except to the extent that I'm about to describe.
All batteries have physical limitations. Among them, operating temperature is perhaps one of the most critical. It's no secret that what used to be called "laptops" are now called "notebook computers" because they get so hot during usage that you can't hold them on your lap—especially when the CPU is working hard for extended time periods. Applied to the MacBook Pro, that means one of the most stressful usage modes for its battery is the condition wherein the machine runs hot for a long time.
My MacBook Pro experienced exactly that condition during my recent system upgrade, in which I had to install Leopard as an intermediate step in order to be able to install Snow Leopard. I suspect that it was the Leopard install that dealt the death blow to the battery. It required lots of CPU usage for a long time, and the battery got very hot in the process. (Of course, it was running on the power supply at the time—which is advisable for a system upgrade.)
During the Leopard install, I checked the machine. That's when I discovered how hot the the machine had become. I had never observed the MacBook Pro getting that hot during any previous usage. I put a couple of heat sinks under it and elevated the machine, but I now believe that by then it was too late.
It's my opinion that the battery simply couldn't tolerate that kind of heat. Shortly thereafter, the two center cells started growing, with the resultant trackpad symptom revealing the problem...and by now you probably know what happens after that. The bulging indicates internal damage to the cells, in which the chemical compounds interact in such a way that causes the cells to expand.
In the case of my battery, I had set it aside and then had forgotten about it while I researched a replacement battery. When I found the damaged battery several weeks later, it no longer looked like the battery in your photos, with some separation of the battery case and cover. I discovered that the damaged cells had continued to expand slowly in the interim, eventually forcing the battery case completely apart. I suspect that if you observe your damaged battery over time, you'll find that the damaged cells continue to expand in the same way.
That's typical behavior for damaged cells, so in that sense, it's "normal". Whether it's "normal" for the cells to become damaged in the first place is more difficult to say, but I suppose that it depends on the kind of usage the battery gets. In my case, I ran the machine with the power supply attached most of the time, I never made it work very hard, and I even used a small cooling fan when I ran the machine outdoors in hot weather. I suspect that's why I got over 5 years of use out of the battery.
But nothing lasts forever, and that aging battery was seriously stressed by the Leopard installation. I'm now convinced that it was its undoing. If there's a lesson to take away from this, it's probably that heat kills batteries. Eventually, the battery will die a peaceful death by exhausting its own ability to hold a charge, but until then you can reduce the chance that it will die violently in the battle of the bulge by keeping it as cool as possible

Macbook pro intel core 2 duo hard drive UPGRADE?

Hi,
Sorry if this has been answered already...
I own a MacBook Pro (15-inch Core 2 Duo), i upgraded to 3GB RAM, and Snow Leopard but my 120 factory Hard Drive seems to ALWAYS drop below 50GB and I want to upgrade.
Any suggestions?
1) Would Apple be able to do this for me?
or
2) should I do it myself?
3) What is the max amount of Hard drive capacity on this mac??
(I called Apple, they told me max is 200gb??...is this true??)
I found a site, that sells them pretty decent prices, any recommendations?
http://eshop.macsales.com/shop/memory/MacBook/Pro/Core2/
4) I've seen videos and read forums on how to install/upgrade myself, but I am reallly not familar with this, and would feel more comfortable if someone could do it for me...anyone here, live or is near New Jersey? that would do it for me? I will pay you.
Thanks!
-T.

To the best of my knowledge the total capacity of HDDs you can installed is only limited by market availability. I am not sure exactly which MBP you have (do you mind including the processor speed in your profile?) you can safely add up to 500 GB HDD. Here is a list of available drives at OWC. The drives may be available for less elsewhere if you check. Take a look at this discussion topic.
should I do it myself?
If you have basic mechanical skills like knowing how to use a screwdriver, and you have a gentle touch, a bit of patience and a steady hand, you can do it yourself. You will find step by step directions with pics at iFixit. Select your particular computer and then click on HD Replacement. I will list some tips at the end of this post.
If you still need to have someone do it for you after reviewing the directions and tips, please post back for suggestions.
Here are few tips you may find helpful:
• Print out the ifixit directions as well as the screw guide ahead of time.
• Be sure you have the right tools. You don't want to damage the screw heads or you may never get them out. And the Torx screw driver is critical. For a spudge I use the handle of an old toothbrush (choose one made of hard plastic), cut off the brush and bevelled the handle end like a flat blade screw driver). For some spudge jobs a credit card will do the trick.
• Picking up on one user’s suggestion, I clicked on the pages of each step which involved removing screws to enlarge, then printed out the pages. I poked holes in the paper where the screws were removed, poked the screws in the holes and stacked the pages in order in which there were removed. Reassembling was a lot easier. No cups to tip over and spill. No guessing. Each screw was exactly in the right place. You can use an ice cube tray, egg carton, dixie cups etc. I previously used small medicine cups one for the screws in each step. I nested them so that the last ones out and the first to go back in are on top. (Some users report cutting up the screw guide and placing the applicable section in each container.)
• Be very careful pulling out leads. Hold the lead as close to the plug as possible and wiggle (the plug ) to loosen its grip. Don’t hold the wires and pull as that can damage the cable, or worse, in some instances pull the wires out of the plug. Indeed, some users have pulled the socket off the logic board! Use needle nose pliers or tweezers if you can access the plug, or nudge the plug with a small instrument to help loosen its grip.
• Use force gently in removing parts. Separating upper and lower case takes some doing. Use a plastic tool (spudge) so as not to leave marks.
• Refer to the screw guide when reassembling computer. Putting longer screws in the wrong place can perforate the circuit board.

Macbook pro hasnt worked after I installed Yosemite when it first came out

Hello,
Irritated, upset and lost. I have found myself the last week or so feeling those 3 words.
What happened? I downloaded Yosemite the day it came out. (the free upgrade) I didn't think Anything of it. figured just like maverick it was perfectly fine to upgrade seeing as it was in the app store. So, me being a naive and clueless (first time purchasing a mac) I upgraded my MACBOOK PRO - Mid 2012 Edition.
it ran through the update, check to see if my mac could handle it. everything was perfect. life was good.
Day 2- turned on my computer went to do some homework, check emails etc (life of a student). I noticed that my mac was a tad laggy. took long to open my apps, safari etc. I thought maybe turn it back off and re open. NO! that just made it worse. it took around 3-5 minutes to LOG ON after i typed my password. Now i was getting worried.
Day 3- same issue. face red and curse words were being fired. I went online to apple support. found ppl having similar issues. So, cleared my disk, repaired permissions, uninstalled the whole shebang. Cleaned it completely. Like the day i bought her. I installed Mountain lion (took over 12 hours) yea over 12 hours thats when i was wondering what is going on.
Day 4- called support they told me to clean it up and try an "internet install" (cant remember the name) i did it. after all the downloading etc. it worked perfect... or so i thought. 2 days later it went back to the same old laggy issues.
Day 5- sat and cried
day 6- looked at the computer with disgust and anger. searched the internet for help. people having similar issues but not as bad as mine. did what they did still nothing
day 7- buddy took a look at it. computer guy, (why didn't I go to him first. well,he was free on day 7) he has been trying his magic. nothing is working. he has an idea of what apple will be doing.putting my computer on an external hard drive etc... lost me after that. Made an appointment with apple genius bar (also, only day they are free/ no warranty, how convenient that it happens)
can a genius help me!!
its on mountain lion basic version when I bought it.

Why is my Macbook Pro very sluggish after the Mountain Lion update?

It's quite frustrating being as this is my first Apple laptop. I figured that it would be easy to update these things.
I was using the prior OS and it worked just fine. Now my Macbook is just as slow as the HP laptop that I had to retire.
I'm using OS X Version 10.8.1
Processor: 2.3 GHz Intel Core i5
Memory: 4 GB 1333 MHz DDR3

With only 4GB of RAM, how much do you have devoted to the virtual machine running under Parallels? Even if it's a small amount, it's going to make page outs and swaps used very high. From my perspective, 8GB of RAM is the 'sweet spot' for running Mountain Lion.
I'm assuming that you've a 15" mid-2010 MacBook Pro? If so, you can speed things up by installing the maximum 8GB of RAM. Go RAM shopping at Crucial or OWC.
Other than upgrading your RAM, the only thing that you can do to speed up your machine is to install a SSD. You can also check the SSDs at Crucial and OWC and decide if one is right for you.

HT5639 Unable to install windows 8 in my Macbook pro 13" .. after the upgrade ..:(

I have updated my Mountain Lion (10.8.3) yesterday .. which includes the latest Bootcamp update which allows the user to install Windows8.
Am unable to install Windows8 .. "Windows 8 is not supported on this Mac" .. My MacBook Pro is ..13-inch, Mid 2010.
Any idea ????

Welcome to the Apple Support Communities
See > http://support.apple.com/kb/HT5634 Mid 2010 and newer MacBooks Pro support Windows 8, except the Mid 2010 13-inch MacBook Pro, so unfortunately, you can't install Windows 8 officially on your computer.
However, Windows 8 is completely compatible with your computer, but Apple didn't want to provide compatibility for your MacBook. There are some guides in Macs forums (I think there's one here) that helps you to install Windows 8 on your unsupported computer through Boot Camp, installing the Boot Camp drivers, too. Do that at your own risk

My Macbook Pro (2011) freezes after the apple login logo appears. The screen just goes white. Please Help

When i start up the laptop, its proceeds normally with the chime and apple logo, but after that the screen goes white and nothing happens. You can hear the sound from within the machine become louder too.. Sometimes it proceeds to login fully but then there are times that it freezes whilst i am using it. It is currently working now as im typing this.. Please help

I would first try booting into Safe Mode then restarting normally. This will be a longer startup than normal in both safe mode and normal boot. That is normal.
I would then repair your drive and permissions:
Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
If the problem is not resolved, then create a new admin user account. Set this account for auto-login. Then try restarting the computer.

My MacBook Pro can't send mail since Yosemite upgrade. I keep getting a message that the certificate is invalid, and it says that my account is "offline." This never happened before, very upset.

I upgraded to Yosemite yesterday afternoon on my MacBook Pro. It was an upgrade from the most recent Maverick version. I had already sent out several emails that day, but once the installation was complete, I couldn't send any mail at all. I kept getting this strange dialogue box that said the certificate for the server was invalid, and might be something "pretending" to be my server. It also keeps telling me that my email account is offline. The only account it shows as active is a Verizon POP account, but that doesn't work. I've tried using the Edit functions and the "doctor" functions, but they seem useless. I tried Help, but the instructions it gave included onscreen items I don't seem to have. This is awful, I've already missed deadlines and am desperate.

I have the same issue. My computer has also slowed down. I hope this isn't a malware. I haven't input my password into it, and dont know what I did to turn this on.
Hope someone else can give some insight

Macbook Pro battery drains way quicker since Yosemite upgrade

Macbook Pro freezes often after the hard drive replaced

Hi I just had the hard drive of my 17" mbp replaced at the Apple Store. The reason I brought my mbp in was because the Disk Utility couldn't fix my HD's problem (loud noise, extremely hot, slow..and disk utility couldn't run repair), and the genius bar person suggested I replace the hard drive.
However after I had my compter back, even though it is not as hot as before and the Disk Utility showed everything is normal now, the really loud fan (possibly fan I guess) noise still sounds very crazy. I was just doing some web surfing, light work stuff, but the HD area just roared. Also my computer freezes so often now, and apprears busy (showing the rainbow color spinning ball) quite frequently even when I am just using Safari and Mail. This is quite annoying and makes me worried more.
Do you guys have any suggestions? I could bring it back to the store again but it was really a trouble. Any ideas will be highly appreciated. Thanks!!

Thank you both. Before I take it back, I would like to confirm one last thing: how often should the mbp make loud fan noise? Or actually we should never hear the fan noise? I really don't remember when I just got this computer (June 2006) I used to hear fan running like this. But I do know if the CPU was too busy while I were using Adobe programs or play WOW or somehing on my old computer, the fan of my old computer (PC) was pretty loud. I am just wondering if the situation I am experiencing is normal or not before I send it back. Thanks!

IMac 27" or Mac Pro Quad-Core?

Hello all,
I understand that this topic has been covered before although I am still unsure and I am looking for some help please!
I am currently looking into purchasing a new computer to complete my architectural post-graduate degree. I currently use a PC, which I have done so for many years and initially I was thinking about buying a customisable Dell XPS sticking to using PC’s. Having recently been sent an email from Apple regarding student discounts offered on the Mac range I thought I'd look into getting an Apple having heard nothing but praise and also that it can also run Windows XP (via ‘Bootcamp’). This would mean I would effectively get 2 “computers” for the price of one, however, after hours of research, scrolling through web pages I am torn between the Mac Pro Quad-Core and the iMac 27” (Intel i7) !
I mainly use Microstation V8/AutoCAD, Maxwell Render, Adobe Photoshop/Illustrator/InDesign, SketchUp, etc, and require a computer which can run programs quickly and efficiently, including some rendering. I will be switching between both operating systems, but will heavily use Windows to run most of my software.
I was first hooked onto the iMac due to its sheer simplicity, elegance and also the specification (Intel i7) which was on par with the Dell I was considering. Although reading deeper on various forums, articles, I found that the Mac Pro Quad-Core might be a better alternative for future proofing (IE. Upgradable hardware) but it costs a little bit more than the iMac plus no monitor included. I feel that the iMac will suffice for what I need but I am not sure how about its longevity. I will be using the computer intensely for the next year, however, after I graduate I will see the computer being used casually.
Another question is, if I were to use Bootcamp how would I share drivers (printers and scanners) between both Windows & Mac OSX? Also, when running Windows OS, would I need to install anti-virus software just like a PC?
I am wondering if anybody could shed some light, assistance, experience and guidance to help me with my purchase please.
Many thanks in advance!

I would say a lot of it depends on just how extensively you expect to be using it after you graduate. Either system should carry you through a single year easily, but the Mac Pro obviously has the expandability advantage that will help extend the tail of its useful life.
IMO, a reasonable expectation for an iMac is 2-3 years, while a Mac Pro is 3-4 for the quad core, 4-5 for the 2x4-core, and if you're buying one of those 12-core systems, odds are you're doing some serious number crunching and you'll be replacing the thing pretty quickly.
So, if you think there's a better than 50% chance of needing to keep this computer for a longer than 2-3 years, go for the Mac Pro, otherwise you can get the iMac now and see where life has taken you in 2-3 years.
As for bootcamp... Think of it like dual booting on a PC. Bootcamp does NOT allow you to run both operating systems at the same time, it's one or the other. Think of it like a time share. Programs like VMWare and Parallels let you run Windows in a virtual machine, but odds are you won't want the performance hit the emulation brings with it. So, there's no need to share drivers, because you'll need to install drivers for all hardware on both operating systems. You'll just need to make sure that any hardware you buy will work with both Mac OS X and Windows. When you're running Windows, it's no different from as if you had bought the Dell you were contemplating. Everything you would have done on the Dell as far as security software, you should do on the Mac with bootcamp. Mac OS X doesn't necessarily need AV software (yet), but Windows absolutely does.
