HT1338 my MacBook running OS X Lion keep slowing down Or freezing up when running safari or ITunes
this MacBook keeps freezing up and I have to restart it when I run safari or iTunes.
I am having similar problems on a Mac mini but everything related to my wifi connection goes to heck'll. Upgraded to 10.8.3 on Wed 10 Apr computer wireless capability lost about 15 minutes later. This configuration has worked for the last 18 months until I upgraded to 10.8.3 two days ago.

PC slows down after a while when running labview application
I have a labview 6 application which is monitoring some data on a feildpoint module, after a while this application slows down and there is a lot of activity on the hard disk drive, also the cpu monitor says 100% activity.
Is it something to do with the PC or is it some other reason?
Thanks
AllanAllan,
My first guess is "Who know's" without seing your VI and probing around; but, to get you started, run your VI and use Labview's tool "Profile VIs..." [Tools... Advanced...] and monitor memory and timing statistics. You may find a constantly increasing use of memory or a VI that consumes an unusual amound of processor time. Then you can troubleshoot from there.
Good luck with it, Doug -
Is it possible to mirror the display on the Macbook pro which is two years old to my iMac which is four years old? Macbook pro is running OS X Lion 10.7.5 and the iMac is running OS X 10.6.8 (10K549). Neither of them have Thunderbolt ports.
OK, well I would go with what Apple says in writing but if you want to take a trip to visit the Genius Bar that won't hurt.
Good luck, I'm 99% certain you will find I was correct but please let us know.

I have seen so much response about the Mountain Lion update slowing down computers. I am updating from Mac OS x 10.6.8. What can I do to ensure the upgrade will go fine? Do I unplug my external hard drive before installing, or keep it plugged in?
Also, I have the 08 version of iWork. Will this cause problems for the update? Can I update this AFTER I update the processor?Welcome to Apple Support Communities
There's no reason to think that Mountain Lion will slow down your Mac. Just make a backup of your data before upgrading with Time Machine > http://support.apple.com/kb/HT1427
Also, check that your apps are compatible > http://www.roaringapps.com Upgrade them to a compatible version or delete them before upgrading.
The external drive won't make the OS X Mountain Lion installer fail, but it's better to unplug it during the upgrade.
iWork '08 is compatible with Mountain Lion. iWork '09 includes OS X Mountain Lion features and can be purchased at the Mac App Store.
To upgrade to OS X Mountain Lion, I recommend at least 4 GB of RAM. You can check how much memory you have in Apple menu > About this Mac -
Safari keeps dropping down this error message when ever i try to log on to any website safai can't verify the identity of the website ( e.g.. any address ) and the drop down has three choices to click on or else you can't go foward., they are check certificate ______ cancel ______ continue.... This thing is so annoying when trying to go somewhere i just want the error message to go away.
In your Keychain under 'login' delete the VeriSign certificates and then quit and restart all browsers/itunes/app store.

Can't help with your Safari issue, but if you want to report this issue to Apple's engineering, send a bug report or an enhancement request via its Bug Reporter system. To do this, register as an Apple Developer—it's free and available for all Mac users and gets you a look at some development software. Since you already have an Apple username/ID, use that. Once a member, go to Apple BugReporter and file your bug report or enhancement request. You'll get a response and a follow-up number; thus, starting a dialog with engineering.

I have a iPhone 3GS but the volume keeps going down till its off when playing songs. Help!, I have a iPhone 3GS but the volume keeps going down till its off when playing songs. Help! I didn't have this problem before. I am listening via the speakers of my stereo. I have done that before but never had a problem like this before.
Thought it had worked but soon found out it had not.
after further days of trying finally, solved it for me Yesterday.
turned off notifications when locked, and bingo, wow.
i have not turned off iCloud but location services are also off.
best thing to do I found was keep checking your usage, settings, general, usage, and flip down to bottom, if the standby and usage are similar there is a problem, if there is a big difference then all is ok. Just keep turning things off and on until the difference is very apparent.
something on my phone was keeping the phone alive even when turned off, and I think this was the phone repeatedly trying to update continually.
to me this is definitely down to the iOS, my wife has exactly same phone and iOS but hers doesn't have any problem and the battery lasts for days.
the guy at the Genius Bar told me to restore the phone via iTunes, not iCloud. This is because iCloud remembers the exact info from your phone and simply reinstates it when you restore, and this includes the iOS too.
when I get home from holidays that's what I'll do, or wait for iOS 8 in few weeks. But I'm so pleased I finally made it work, I was beginning to think ditch the phone and buy Samsung.
anyway anyone out there please try my final solution and let me know if it works for you? -
HT1338 can I upgrade straight to lion without purchasing snow leopard if I am running on OS 10.5.8
can I upgrade straight to lion without purchasing snow leopard if I am running on OS 10.5.8?
Well, yes, if your Mac meets the requirements, you can afford to erase the drive completely, & don't mind paying $10 more for Lion on a Flash stick than Snow Leopard/10.6 on DVD & Lion/10.7 download from the App Store is.
Snow Leopard/10.6.x Requirements...
General requirements
* Mac computer with an Intel processor
* 1GB of memory (I say 2GB at least)
* 5GB of available disk space (I say 30GB at least)
* DVD drive for installation
* Some features require a compatible Internet service provider; fees may apply.
* Some features require Apple’s MobileMe service; fees and terms apply.
Which apps work with Mac OS X 10.6?...
http://snowleopard.wikidot.com/
It looks like they do still have it:
http://store.apple.com/us/product/MC573Z/A?fnode=MTY1NDAzOA
If it's a core Duo & not a Core2Duo, then it'll only run in 32 bit mode.
Snow Leopard/10.6.x Requirements...
Lion/101.7 System requirements
• x86-64 processor (Macs with an Intel Core 2 Duo, Intel Core i3, Intel Core i5, Intel Core i7, or Xeon processor.)
• At least 2GB of memory, (I say 4GB)
• Latest version of Mac OS X Snow Leopard (10.6.8), with the Mac App Store installed
• At least 4GB of disk space for downloading, (I say 40GB at least)
Like Snow Leopard, Lion does not support PowerPC-based Macs (e.g., Power Macs, PowerBooks, iBooks, iMacs (G3-G5), eMacs).
Lion also does not support 32-bit Intel Core Duo or Core Solo based Macs. Rosetta is no longer available in Lion, which means Lion no longer supports PowerPC applications.
Or, if you can afford to erase everything & spend $10 more than the 10.6 Disc & 10.7 from the App Store...
Or if you can erase your disk...

Macbook pro keeps slowing down
My Macbook pro had been playing up lately. Looking at the activity monitor the Memory Pressure keeps going to red and slowing the computer down. A Safari Web
Content process keeps opening up and causes it to use up all the RAM, slow down and a few times caused it to crash. The process is https://autotrader.portal.com. How can i stop this from running? Every time it opens up by itself I have to force quit it to stop it slowing up and freezing.Remove all references to the site in your Reading List and in Top Sites.

I have just bought a macbook pro 13" with retina display and a 27" thunderbolt display to go with it.
I plug in the display, set it all up to the look and format that I want to use (same for both displays, I am using the mirroring feature), and then when I unplug the macbook from the 27" display it's settings revert and I can't see half my windows as they fall off the edge of the smaller macbook screen.
Is there a way to make the macbook keep the same display settings, even when I unplug it from the 27" display?Not that I know of... but if someone comes along with a method, I would certainly be interested...

Mountain lion update slowed down my macbook pro
hey guys,
I just updated to mountain lion
however, after the installation, my macbook pro has been noticably slow.
slow booting, slow when operating installed programs, chrome/safari got slowed down as well.
Also it freezes for couple of seconds and i was wondering why.
If any of u r experiencing same problems or know how to fix it please kindly let me know!
Thank you!Have tried everything possible, repairing permissions etc to no avail.
You haven't tried everything possible or you would have a solution. If you tried the most extreme possible solution (erasing the hard drive, then reinstalling the system and nothing else) and still had the same problems, you would have discovered that you almost certainly have a hardware problem. For some solutions that you haven't tried yet, I'll refer you to the same two links I referred sylee48 to.
As for that article, that's an extremely unprofessional piece of writing. They publish - as if they were fact - the conclusions of untrained, non-technical users who do not have the necessary expertise to make such conclusions. And they concluded that these were bugs that Apple should be working on.
In fact, this may be one of the smoothest upgrades I've seen in a while. (Boy-oh-boy, you should have seen the screaming here for the Snow Leopard and Lion upgrades! It's positively peaceful in this forum compared to that.) -
Macbook keeps slowing down and crashing
Hi,
I started having this problem about 2 weeks ago. Everything was working fine, then out of nowhere, my macbook froze. I waited for about 10 minutes, then I turned it off. When I turned the computer back on, it was EXTREMELY slow. It took 15 minutes just to boot, and after that, even when i just moved the cursor, the rainbow wheel would appear and keep spining for 20 minutes. It was impossible to do anything. So I decided to restore the hard drive from a backup I had. After I did that, it worked fine for a couple hours, then the same thing happened. Then I did some research and concluded that my hard drive was dying, so I got a new one, restored it from my backup and replaced my old hard drive. But after a few hours same thing happened again.
So I know the problem is not related to the hard drive. Also, I everything seems to work fine when I boot from an external hard drive. Only when I replace and boot from the internal hard drive connection, the slow down occurs and eventually gets to a point where I can't do anything with my computer. Sometimes I can repair it using the disk utility and diskwarrior, but it doesn't last long, eventually it starts slowing down again and then the same thing happens. The operating system doesn't make any difference either. It happens both with Leopard and Snow Leopard.
I'd appreciate it if anyone knows what would be causing this problem.
Thank you.How much free space on the drive?
Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure you always have a minimum of 15% free disk space.
I have more than 50% free disk space. I did have some slowing down problems before because of disk space, but this time it's different. It's not a regular kind of slowin down, it slows down so much that it becomes imposible to do anything. Even when I just move the cursor, rainbow wheel appears and doesn't go away for 10 minutes.
But thank you anyway. -
MacBook slowing down & even freeze at times.
Hi everyone, it's ben nearly two years that I've got my macbook and it's slowing down and even at times freezes. Although i use iceclean regularly it still is slow...can anyone advise what can be done?
I'm not sure what you want to do - diagnose the problem, or erase your Mac and reinstall OS X.
More information would help. Rather than ask a dozen additional questions please consider the following:

Internet speeds keep slowing down to a crawl
I'm having a problem that has only developed in the past week which was during a time when I haven't changed any configurations in that period of time since my son was born a week ago yesterday and I obviously had more important things to do than mess with my network configurations. However, about 2 weeks prior to his birth, in the process of configuring a baby monitoring system with icam source, 3 weeks or so ago, I read that I might be able to improve my internet performance, I ran googles namebench a couple of times and added and re-ordered the DNS servers that had been listed prior to any problems developing based on its' reports. My internet speeds improved as a result of changing those DNS settings and stayed good until the past week. But of course, we now need to use the computer as part of our baby monitoring system and it's not working worth a **** and I'm getting frustrated since I can't put my finger on the problem and I don't really have time to spin around in circles right now. I'm sure it's probably something simple and I can't put my finger on it though. Sleep deprivation is new to me.......
I've kept running log of notes so this is a little deshoveled but I figured the more information I provide the better the chance someone might help me get this solved quickly.
In the last week, since my sons birth, my internet speeds would be okay after restarts and resetting everything, 2.5 Mbps or so but after a 10-15 minutes it starts to slow down to .2-.3 Mbps. I went thru all my network settings, restarted everything, repaired permissions, I've changed ethernet cables reset PRAM, firewall is running, stealth mode enabled, allow signed software incoming connections and my various other programs such as netsessionmac4f3c6b, skype, java, itunes, etc.
All sharing services off and pretty basic login items at startup including growl.
I had AT&T come out and check my DSL line and everything checked out on their end up to and out of the DSL modem based in their equipment tests.
The problem seems to start when I connect my imac (a fairly loaded 27" imac I got in Dec.) First off, as soon as the imac is connected to the modem via ethernet, the old ethernet modem flashes and continues to flash, even right after startup. So the tech thought something was running in the background and I can't figure out what. I looked through login items but don't see anything that would be a problem and am afraid to eliminate everything.
So I created a guest account to eliminate any login items (I think) and in I got 5.69 Mbps right off the bat. But after a minute or two, without changing anything my download speed slows down and I get for example .77 Mbps. The same thing happens with my administrator account on the imac. Fast speeds at startup and more importantly if I change the configuration by switching between ethernet and airport, I get fast speeds right after changing the configuration but after a minute or two I am well below 1.0 Mbps. I've got several network configurations with automatic, airport and ethernet set up in different ways including a clean ethernet connection with the original DNS settings.
I haven't set up an airport only account but that really isn't the way I want to hook up the computer that sits right next to the modem and runs my network. Restarting the old modem and direct connecting the computer to the modem results in the same thing happening.
I connected my ethernet from the (old?) modem directly to my ancient powerbook G4 and I got +5.6 Mbps download but it also slowed down to 300 kbps after 5 minutes or so the first time (old modem?)
Now to explain why I have "old?" listed above. I was then able to get a new DSL modem from AT&T, hook it up just fine, get enormously faster internet service in the 5,000 kbps only to have it slow back down to around 300 kpbs after connected for several minutes.
directly connected to imac-bypassing router
3,500 kbps
after 15 minutes-250 kbps
connected to imac thru router/time capsule with airport extreme
2500 kbps
after 15 minutes=166 kbps
directly connected to an older powerbook G4 with new modem
IP address of 192.168.1.64
5.65 Mbps on speedtest
after 15 minutes=5.67 Mbps
after 30 minutes= 5.59 Mbps
1 hour-5.66 Mbps
Very solid, stable readings for what I am used to. This would seem to isolate the problem to the imac.
directly connected to imac with new modem
IP address of 192.168.1.64
5.8 Mbps on speedtest
after 30 minutes= .60 Mbps-ping takes 250 ms
1 hour= .46 Mbps-ping takes 250 ms
Now a problem that only started last night after I hooked up the new modem and started up my old Time capsule/airport configuration, I got a message that said something to effect of "another device on this network is using computer IP address 192.168.1.64. So I tried manually changing last digit of the IP address on the computer to one number higher and it kept saying the start and end range were incorrect so I shut the airport station down since when it was connected, it would not allow the computer to connect thru the router via ethernet. I did a hard reset on the airport and I got it back up and running just fine but the internet speeds on the imacs' ethernet connections are so slow it's practically worthless. I also checked to see what was connected to my airport on any given occasion, 2 iphones, 2 pads, another imac running upstairs and a newer powerbook running icam source that is supposed to be the baby monitor. Except for the laptop everything can use "802.11n" but the powerbook only connects via 802.11g so I have set the airport to that limiting setting.
Any suggestions? Is there a way for me to log what is happening so I can report in more detail?First thing is to check if the wireless is on a sensible channel: HomeHub doesn't always make sensible choices. Install inSSIDer on your laptop and see what other devices there are around and if there is any clash. Also, try moving the HomeHub around a little, even quite small differences can make a big difference to wireless signals.
You could run an ethernet cable from downstairs to upstairs. Easy to do, but can be a bit unsightly. If most of your devices are upstairs, you could use this cable to connect the modem to the HomeHub. If you have devices both up and down, you may want to keep the HomeHub downstairs and add a switch upstairs.
HomePlug may be suitable for you. If you search Amazon for HomePlug you will see a couple of kits for just over £30. Don't go for an 85Mbps one. A 200Mbps such as the TP-link or D-Link should be much better than wireless, but not as good as a cable.
Depending excatly how many devices you want to connect and where, you can pay more and have a builtin wireless at one end: http://www.amazon.co.uk/Devolo-1408-Wireless-N-HomePlug-Adapter/dp/B00472MMCQ/ref=sr_1_15?ie=UTF8&qi... Or it may be best for you to use the basic devices and add an old wireless router in switch mode.
