I'm having trouble with my new macbook pro where in some applications after scrolling down and stopping, I sometimes am unable to resume scrolling. I have tried shutting down the application, rebooting but nothing seems to work. Whenever this occurs I am still able to scroll fine in pages and safari but the preview app and xcode have been problematic for me.

I have an Unibody MacBook. I've experienced that under OS X "Tap to Click" function of the trackpad stops to work after "some" usage. Then I go to System Preferences, disable the feature, reenable it and it starts working again. OS X is updated and firmware updates are all installed.
10.9.4 mavericks macbook pro retina to TV via HDMI using an HDMI cable to watch movies on my laptop macbook pro retina. was working this morning, and watched a movie. then I go to work, and come back and now the exact setup is no longer working. it does not show any display in the preferences menus, and the TV is just blue without any input. cable is secure, nothing has changed. nothing.
edit: actually I did pull the HDMI cable out while the two were connected this morning.
tried restarting, reconnecting, nothing ... Why computers suddenly stop working for no reason whatsoever. maybe someone hacked my computer this afternoon while I was gone? it's just a random failure.

I have two shares that are always connected on my mac (two folders via smb share). They are NAS devices. They are also connected on numerous other macs in the house. On my mac pro, once in a while, I will click in the share and nothing happens. I will disconnect the share and then try to reconnect, and I just get "Connecting to server" forever (until I cancel). A reboot does the trick, but a reboot is a pain because I have two VM sessions, numerous jobs in queue, etc.
Is there a way to restart that daemon that handles smb mac shares? I already tried to stop and start network services.
My wife's macbook pro, 2010 circa, is not rebooting. With three attempted power-ups she gets a grey screen with the Apple logo...
View 2 Replies View RelatedMy computer will start running really slowly and then the keyboard stops working, then after 30 seconds or so I lose the ability to click but the mouse still moves. Command-option-esc for force quit still works some of the time though but refreshing everything from there doesn't help. After I reboot everything goes back to normal. This has happened every other day or so for about a week.

My trackpad is not responding. I have to reboot and then it works for a few minutes then completely stops. Keyboard is fine. I need to use a mouse.

I'm really struggling to understand why my 2010 mini has trouble playing some QT videos that my 2006 mini handles just fine! The two machines are:
Macmini 1.1 (1.83 GHz)
intel Dual Core
Memory 2GB
Bus Speed: 667
Graphics Card GMA 950
VRAM: 64MB
[code]....
The problem first presented itself as I am working on a generative video installation using Max6. I've used the older mini for the installations for some time with very few issues. I've been using the newer mini for video processing, compression, and editing and making DVDs and blu-ray disks. No issues there that I have noticed either. However, when I recently tried to use the newer mini to run the generative video, I noticed that several of the videos were stopping and then starting up again (skipping). I know that Max can sometimes have trouble with videos due to processing issues - but why would it work fine on the older, less powerful machine and only have issues on the newer one?
To begin troubleshooting, I ran one of the videos in Quicktime on the newer mini to see if similar issues arose, and they do. No problem on the older mini. The video is formatted in DVCPRO50 anamorphic format, and I am using the same monitor in both cases (1440x900,60Hz), connected by VGA to the monitor PC input. I know that Quicktime can have similar issues with very large files sometimes, but I still don't see why the newer machine stumbles with the same video that runs fine on the older one.
I've been hoping to start using higher resolution videos in this work, but am worried that if a newer machine can't handle these SD videos, HD will be worse. I like the minis for installations because of their small size and portability.
In the last three days my iMac desktop has begun starting itself up. There is an audible beeping (three or four beeps) and the on/off indicator light blinks rapidly. When the screen comes up there is no desktop but a gray background with reboot instructions. When I type the reboot words "mac-reboot" the desktop comes back.
Under Logs in the system profiler I see the following message:
CGXDDisableUpdate:Updates disabled by connection 0x66-3 for over 1.000000 seconds
and
CGXBlindSurface returns-536870210
The computer is rather old, is running OS X 10.2.8 and has never done anything like this before.
On a day-to-day basis I run: Adobe PS, INDD, and AI, Microsoft Entourage, Firefox and iTunes. Just recently, after an upgrade to Leopard, I added Things and Simplify Media to the list.The problem that happens before (on Tiger) and now (on Leopard) is command+tab switching stops functioning and Expose hot corners and shortcuts stop working.
I'm pretty sure this isn't a Finder crash because before, on Tiger, I could quit+restart Firefox and everything would be back to normal. Almost as if some shortcut had causes the system to act differently or there was some app dissonance?
But now, with Leopard, nothing I quit will cause these two features to act properly until I do a restart. Both features (command+tab switching and expose) are very necessary for my work flow. I have checked SysPref to make sure keyboard shortcuts are default and Univeral Access to make sure assisted devices is turned off.
When I attempt to verify or repair disk permissions the process starts and then stops. The following message appears in a drop down message box: First Aid failed. Disk Utility stopped verifying (repairing) on G4HD because the following error was encountered: no valid packages. My disk verifies in working order. I have used DU from the installer disk and obtained the same resulting error message. I have run Tech Tool Pro's optimization and maintenance sequences. I reinstalled Security Update 2008-003 PPC thinking it might have been the problem. This permissions verification/repair problem and a problem with my firewire external HD and iPod failing to mount started after I installed the security update. (I am not asking for help with the firewire drive problems here - that is for another forum) I am running 10.4.11 on a G4. I guess my next step is to reinstall 10.4.6, the version I bought
View 4 Replies View RelatedI have an old g4 , the kind shaped like half a golf ball, which starts up and then quits at different places during the process. Sometimes with the gray screen and Apple logo, sometime later when the OS has fully installed,but fails quite rapidly after that. Then tries to reboot itself with varying degrees of failure.

I'm yet to figure out a pattern, but my Macbook Pro's keyboard will just stop working for several minutes at a time at random points in time...Even if I hit caps or num lock, they don't turn green. Sometimes it'll just happen once every few hours, but I was in class the other day and it would work for a minute, then not work for a few, than work for another minute, etc.
View 3 Replies View RelatedI received an Acomdata 2Tb external hard drive today from Amazon and plugged it in. Time Machine popped up and I declined to link the hard drive to it. I went into Disk Utility and chose the new hard drive on the left column and went to erase. I chose Mac OS Extended. I named it and hit erase. It started going, and going..... and going... and a half an hour later I knew something was wrong.
Disk Utility was not responding and I eventually had to Force Quit. Now I cannot format the hard drive. I starts and then it stops with a disk error. I tried to run the First Aid verify and repair and both stopped after a few seconds with an error. What do I do?
I've noticed that occasionally my IR sensor stops working, and no longer responds to changing the volume, skipping the track in iTunes, etc. It can be resolved by going into Security prefs, disabling and re-enabling the IR sensor. This is annoying, however, and I'm wondering if it's a known issue that might be fixed.
I noticed that when you disable and re-enable the IR sensor, the last few remote button pushes you made while it was broken come through in a burst.
Quicklook has stopped workingon my MacBook Pro OS 10.6.8. Pressing the space bar on a file yields nothing. Is there a way to update or reset it so it starts working again?

I own a 15 inch mid-2010 macbook pro and have Windows installed via bootcamp. Because of this, I often shut down and reboot the computer into the other partition. I would say I switch between Windows and Mac OS X about six times a day.
Since I reboot often, I was just wondering if doing this does any damage to the hard drive or other hardware.
My newest discovery is that when my computer freezes up what ever sound is playing makes a skipping noise and then I have to kill power to shut off what is the cause or how can I find out is there any log I can run or check to see the last action process that went on?

My MacBook Pro will not start. It chimes and the gray progress bar starts and then the computer shuts off. I am able to start it holding the Command +R keys and access Disk Utility. That is where it says my S.M.A.R.T. drive is "failing". I have a backup from Time Machine from a week ago. I am concerned the computer is going to die. What should I do and is my computer going to die?.

I got my computer yesterday, it's a iBook G4 OS X 10.5.8. The charger worked fine until around six o' clock. Then it wouldn't charge. We switched the power pack and it worked for an hour or so, and then the same thing. What can I do? I CANNOT take it to be fixed.

View 14 Replies View RelatedSo to preface my problem let me just say that ive got my own macbook which works on the same wireless network with no faults at all, so i assume its not an error with the networking hardware.
For xmas i bought my parents a macbook, recently (not sure how recently as theyve only just told me its happening) they can be browsing the web then all of a sudden the internet takes ages to load, it stalls on 'trying to connect' for a long time (40+ for each web page).
Ive tried using firefox and the same thing happens so it looks like its not safari specific, during this time i cannot ping [URL] through a terminal either or if i can the response time is unbelievably slow.
Now, ive tried disabling ipv6, ive set the dns servers to opendns and none of this has fixed it. if i click on the airport utility and turn it off and the back on it fixes the problem for a short period of time before it happens again.
I am trying to fix a friends macbook pro. When I turn it on the screen shows the apple and the spiral underneath it spinning like it should then when it stalls for .2 seconds it goes to a white screen then there is vertical purple lines in groups across the screen. So the screen is white/purple. Then it fades to just white and I cant do anything.
I hooked up my monitor with a DVI cable to see if it was the motherboard that was possibly bad but the monitor works just fine with the cable. I can use the computer with the laptop keyboard/mouse and it works just fine. The laptop screen just stays blank the whole time. I uploaded a vid to utube for it. If anybody has any ideas for me please help. I dont know if this is a monitor problem or the inverter or the motherboard, possibly some other piece of hardware?

The last few days my keyboard and mouse have stopped functioning at random times on my macbook. I am running snow leopard. I have to shut the lid to put it to sleep and wake it up to get it to respond.
