Macbook Air was purchased in June. Worked fine the first few months, but has been freezing progressively more often, forcing a shut down. Cursor active but clicking does nothing. Today it has allowed not functionality and froze upon booting up. It isn't used much beyond checking email and surfing the internet. Also, is it true that MacBooks have a one year warranty?
View 1 RepliesIn the last few weeks my Macbook has started be begin freezing at seemingly random intervals. It is a 2008 Macbook, not a Macbook Pro or Macbook Air. At first this was only once a day, or once every other day, but it has gotten progressively worse. By today, I can't go more than 2 or 3 hours without it freezing, forcing me to manually restart the computer. The freezing is not application specific; once it freezes with one application, if I try to pull up anything on the menu bar, the menu bar proceeds to freeze. I haven't made any recent major changes to the computer, and it had been working perfectly fine before now. I'm working on scanning it in case it is a virus, but this is seeming increasingly unlikely.

For the past month or so, I've started to have some really weird problems with my Mac Pro. Applications will suddenly stall out or freeze up (endless rainbow wheel), and Force Quit won't work to quit them. It happens most often with iTunes and Finder, but it's also happened with Firefox once or twice. The whole system doesn't freeze or stall - I can generally still use another application (i.e. if iTunes stalls and won't quit, I can still continue to use Firefox, etc.), but generally if I leave it this way too long another application with eventually freeze, forcing me to shut down by holding down the power button (Shut Down won't work in these cases).
Occasionally when this happens, I have left my computer alone, and sometimes it unfreezes or unstalls by itself, but this is usually hours later, and sometimes it doesn't do this even after hours of waiting. I ran a hardware test thinking that faulty RAM might be the issue, but the hardware test said everything was OK. I don't know if I should believe that or not. I've tried repairing permissions and verifying all disks, internal and external, and everything checked out OK. What is going on here? Why do things keep freezing/stalling and forcing reboots?
Here is what I've got:
2x2.8GHz Quad-Core Intel Xeon
2GB 800MHz DDR2 FB-DIMM
Running Mac OS X 10.5.8
I have really normal stuff installed - MS Office, Photoshop, Ableton, etc. No really weird third-party applications other than some really simple stuff. I'm not the type to overwhelm my computer with a bunch of crap.
My Macbook keeps freezing and I have to manually force a shut down. What do I do to fix this?

My new 13 inch macbook pro keeps forcing restart. A black box appears and says it the computer must restart. Does anyone know why this is happening?
Info:
MacBook Pro (13-inch, Mid 2012), Mac OS X (10.7.4)
My MacBook Pro early 2011 13" freezes, requiring a hard restart when the CPU temperature stays in the 195 F (as measured by iStat nano) range for more than a few minutes. The fans run appropriately. I am running 16 GB of RAM, most of which is not being used during these 'hot' episodes (according to Activity Monitor). Typically they happen when Mail is trying to connect to iCloud and can't seem to do it. Then the spinning beach ball. Can't force quit or restart from the Apple menu. I'm using 10.7.4 on a dual core i7, 2.7 GHz unit.

I've been testing this method for awhile to determine if it was possible to boot the x86_64 kernel on the Macbook Air via any process. It looks like it is. References here and here show it is possible to force boot the x86_64 kernel if you have a 64bit EFI firmware. To test your EFI firmware you can use the following: (Source).
Type the following into Terminal:
ioreg -l -p IODeviceTree | grep firmware-abi
If your Mac shows "firmware-abi" = EFI64 then you can proceed. If you see EFI32 then you're out of luck for this particular method.
The rest of the process is detailed at the links included above. I will rewrite this part when I have the method fully working, but for now I haven't been successful.
There are several relevant parts such as:
Quote:
Model (with 64-bit EFI) Byte Position in boot64.efi Old Value New Value
Mac mini(Eary 2009)　0�266DB 0�00 0�80
MacBook Air(Late 2008)　0�266FB 0�00 0�80
iMac(early 2008) 0�2671B 0�08 0�80
included in the comments at this page, but so far I'm stuck.
Update 1:
As an alternate method I attempted to use lipo to modify the mach_kernel to only contain the x86_64 kernel information. A reboot confirms this didn't work so well.
Interesting notes so far from the EFI modification tests:
1) bless --info works fine on 10.6.0, but gives a Can't access "efi-boot-device" NVRAM variable on 10.6.2.
2) You can still modify which efi file is used for boot in 10.6.2 (I fouled one up in a hex editor and rebooted to see if it would fail just to test it), but the bless binary will not show the information the system is configured with.
3) The information at both links above for modifying the boot.efi doesn't seem to work in 10.6.0. It already wasn't working in 10.6.2, but there were some comments about it working in previous versions of Snow Leopard so I went back to an unpatched vanilla install from my install media (used Disk Utility to format the drive before installation) to test it.
Thread Notes:
1) Yes, I am aware that Leopard and Snow Leopard are fully capable of running 64bit programs using the i386 kernel. This is just an experiment for fun.
2) No, I do not have any reason to do this and I know the Macbook Air runs fine with the i386 kernel including every feature of the x86_64 kernel.
3) Yes, I know the Macbook Air only contains 2GB of ram so there is no reason to run the x86_64 kernel.

My mac will not sleep without my forcing it.
Have made sure the energy saving settings are ok but it will not sleep when it is supposed to.
Is there a way to force full screen apps to run in a window?

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.
iPhoto, for example, takes about 30secs to open. If I'm using Safari and decide I want to upload a photo, opening iPhoto and then going back to Safari simply means that iPhoto will jump to the front with it's big, blank screen and spinning beachball five or six times. It's like fighting with my Mac. It's like I'm constantly clicking back to Safari and then a few seconds later my Mac will pop it to the front as if to say "You wanted iPhoto, so here's iPhoto - watch it open."
It's very annoying. Can I set something to allow applications to load in the background?
this is driving me insane. On Tiger I was always able to select the default application to open a given file type, but I can't do this in SL. I want the XLD app to always open my .flac files. So, I click on a .flack file, select "get info" and select "Open with - XLD", and then I click CHANGE ALL. Fine. Next time, I just click "open" on a .flac and it's back to some other application being the default for opening the file, and not XLD! It keeps doing that, no matter how I keep trying to get XLD to be the default... what am I doing wrong, and what can I do to get it to work?

My FINDER is behaving erratically - in that, when I create new folders (which I can do with the mouse and right button) it will not allow me to name the file, as if the computer would not recognise the keyboard. What is weird, is that I then click on a web browser, or any other application and I can type as usual.
I assume it is then a problem with FINDER - which after forcing to relaunch, works fine for a little while, but shortly, the problem comes up again
Having to relaunch finder every 5mins is not my idea of a smoothe operating system.
I'm trying to liberate more space - but it is proving difficult as my main tool in order to back up files is finder.
Not sure if this is a Hotmail thing or a browser thing, but if someone attaches a jpeg to an email I recieve in Hotmail, when I click it in Firefox I get a dialogue box asking: What should Firefox do with this file? Open With [choose...] or Save file?In Safari, it just automatically downloads the picture to the default download location and then auto opens it with Preview.This is so annoying! How do I set my browsers to just open jpegs within the browser?
View 7 Replies View RelatedI accidentally deleted my entire exchange calendar. I use entourage to manage my exchange account. I have a back-up of the main identity file from just before the delete. Great, right? Sure, except that when I swap out the current (without calendar data) main identity with the back-up main identity (with calendar data), the data populates the calendar, but then gets wiped when entourage syncs with the exchange server. Specifically, the data disappears when syncing is at the "Updating sync issues" stage (as noted in the lower right hand corner of entourage during sync).
Neither I or my IT girl can sort out how to force entourage to use the local calendar data instead of the blank server calendar data.
Any ideas?

Starting up from any boot disk will give me a kernel panic forcing me to hard restart.
Background:
After many freezes I ran disk utility and I get:
Checking Catalog file.
Invalid index key
The volume Macintosh HD needs to be repaired.
Error: The underlying task reported failure on exit

So I use my wife's Imac startup disk to boot it in order to repair but I get the dreadfull death screen (I know how to press the C) I'm thinking maybe it's because her disk if for her Intel proc so I go and buy a copy of disk warrior 4, and same problem.
Since installing Safari 5, everything seems to be slow. I have also 'lost' the "Glims" facility of forcing the completion of reluctant web-sites. Is it simply an impression, or is the new Safari slower? It seems to get so far with the address-bar and then think about it.

I just bought a new Mac Mini (Late 2014, ships with Yosemite) to replace a defunct MacBook Pro (Late 2008, last ran 10.8.5). I have a local administrative user account and some server and network data that I want to migrate from the latest Time Machine backup of the MacBook Pro to the Mini. I don't want to copy anything else to the Mini. Neither Setup Assistant nor Migration Assistant will let me deselect anything though. All the check boxes are greyed out. Clicking on them does not uncheck them. This forces me to copy everything from the Time Machine backup to the Mini. Then the Mini won't restart.  It won't even boot into safe mode. It just gets stuck in a reboot-loop until I enter recovery mode, wipe the system drive, and reinstall Yosemite.Â

I spilled Gatorade on my MacBook Pro and now if i don't touch the trackpad for about 4 seconds it asks if i want to shut down, go to sleep, or restart. If i don't hit cancel within about 5 seconds it will shut off. It will also shut off if i close it. The only way it stays on is if i hold down the command key.

I'm a new Mac user. A few days ago, I tried to turn my Mac Air off by clicking "shut down" as I always do.But it wouldn't shut down.Moreover, there was no indication that I had even clicked "shut down." No rainbow circle telling me to wait.Days later, I'm still trying to restart or shut down my Mac, and I can't.It's like my computer isn't hearing what I want it to do!I press "shut down" and nothing at all happens.I can, however, just resume using my Mac as usual (internet works, ITunes opens, etc.)I've been browsing forums all day and nothing has helped.
