OS X :: Does Power Loss Damage Batteryless MBP ?
Feb 18, 2009
I run MBP without battery 99% of the time to safe its 300 or so cycles and I occasionally trip the mac safe adapter (which i find gimmicky and annoying) by maneuvering MBP around when sitting down & the cable gets snagged momentarily on corner of coffee table etc and out goes the power !!
Is this causing any damage ?!? I havent noticed any ill effects.
I also understand from reading other threads how the processor speed reduces without battery but thats ok considering most of my use is limited to web browsing..

I am using an external hard drive with Airport Extreme for Time Machine. Should I be worried about my data in an event of power loss because the drive is always mounted? Has anyone loss a drive due to power loss and what have you done to fix it or prevent it? What are you using as backup power and why? I know I can go with Drobo, but are there other lower cost options?

For the past two weeks or so I have been getting a lot of Kernel Panics. Most of them happen when I select Restart or Shutdown. There have also been cases of Final Cut Pro crashing regularly, but I think the Kernel Panics are far more important to diagnose. I have not changes any hardware for at least a year. The machine has 4.5gb of RAM and 40% of the system drive free. I have run Disk Utility to repir the disk as well as the permissions, all coming back with no errors. The only thing that I can think of that changed is that I purchased and ran Disk Warrior 4. It seemed to help tremendously with performance, however, it is the only thing that I can think of that has changed. I am also suffering from some performance loss as well. I get at least one Kernel Panic a day. I have no idea what the KP mean, but they all look similar.

G5 Dual 2.5ghz
Mac OS X (10.4.10)

Hook up a $3K machine to a $1.5K display and have to hard power down your $3K machine to get the picture back.When I boot everything is fine. If I change input to TV or power off the display, when I power back up or switch back to hdmi input screen displays error, can't read signal check output device. I have read on this forum about a issue similar with ATV but not with MacPro. In my google searches I read some issues with Vista, but no resolution... thought to be a ATI driver problem. Does anyone know of a tweak to fix the ATI 2600 XT to remember the tv signal after you change inputs or power off the display?

i accidentally hit the power switch on the wall during an upgrade (might even have been a firmware upgrade, I didn't really look at what was going on). Anyway, now it hangs on the silver Apple logo screen with a spinny wheel on reboot. It's only 3 months old, it's the $599 model.
What to do? I see that you can download firmware restoration disks but they appear to be limited to earlier versions of the Mac mini.

Mac mini, Mac OS X (10.7), I think the OS is OSX 10.7...

I recently tried to install OS X Yosemite. unfortunately during the install my laptop was unplugged and the installation failed mid way through. Each time I start my mac I get to login screen and after logging in get an error message and told to restart and try again - which does not resolve the issue. Guest login do work to the safari screen.
The error message reads: You need to restart your computer. Hold down the power button until it turns off, then Press the power button again. Behind system code, including:

Using Macbook Air, get low battery warning. Finish what I'm doing, close screen at 0:00 remaining time. Apparently it didn't sleep in time before battery drained completely, since when opening after plugging a minute or two thereafter it went into cold restart. (Btw, I've had the machine just shut down instead of going into deep sleep on low battery a few times before, would like to fix this too...)
All my programs reopened, except Mail loaded the "Welcome to Mail" splash screen, with my name and one of my email addresses autofilled, but none of my regular accounts. I canceled and it closed. Repaired permissions, verified disk, no problems. After searching the forums, turned invisible files on, fired up my Time Machine backup, and restored a recent pre-crash version of Mail preferences plist in user/Library/Preferences. Start up Mail again: same "Welcome to Mail" splash screen.
Called Apple Care, they wanted me to do a full restore from Time Machine backup. But my backup is a week old and I will lose data not covered in the meantime--I still want to find a way to get Mail back working without doing this. The only other suggestion was clear caches, restart, try again. I fired up Onyx, executed maintenance scripts, rebuilt Mail's envelope index, cleared system and user caches, and still no dice.
how to get Mail to recognize my old preferences plist instead of heading straight to the splash screen? To restore to all my email again without a full restore from week old back up?

Loss of storage. I have listed below a summary of my hard drive:
15.02 GB free of 59.44 GB
Other: 36.33 GB
Apps: 6.52 GB
Photos: 1.02 GB
Audio: 458.9 MB
Backups: 51.8 MB
Movies: 46.8 MB
I had downloaded a few films accidently onto my hard dive rather than an external drive, after deleting them from the hard drive I noticed that the "Other" had increased significantly.

I just bought my MBP, It came in on 9/3. I'm not sure if I should be concerned by this or not.
I've had the MBP for 4 days total. Watts and the System Profiler both show that I've had 6 cycles. I'm down to 5506 mAh from 5770 mAh, and I have 95% health left. If it continues at this rate, 95 days (or cycles) or so I'll be down to a useless battery. I performed a cycle 2 days ago.
I use my MBP as such - I charge it to 100%, sometimes I'll continue to use it on the charger, other times I won't. After its charged, if I leave my room with it, I won't charge it again until it gets down to 40% or less. I'll plug it in at the end of the night, and let it charge up. Sometimes I'll take it off the charger once I go to bed, other times I'll let it charge throughout the night.
I've searched around, and haven't found a similar issue. Most of the ones I see are after a few months they are having battery issues. The Battery FAQ doesn't really answer this question for me.

I have two USB hard drives connected to my iMac. Since installing SL, I have experienced data loss on both. Example: I open a folder in the Finder. I then CMD-UP to move to the next level up, only to find that the folder I was just viewing is no longer in the list.

For example, if I take an album that's ripped at 320 kbps, archive it all into a .zip using Finder, is there any quality loss?

I recently got a new MacBook Pro and migrated from my older MacBook Pro using the Migration Assistant. I'm running 10.5.7. Pretty much everything transferred OK, but now when I log in to my user account on the new machine and try to run launchctl load ..., I get the following error:
launch_msg(): Socket is not connected
These same launchctl commands didn't use to cause an error on my old machine before the migration. Also, launchctl works fine as the root user.
The user ID, login name, and entire directory structure are the same for my user account on the new machine as they were on the old machine; nonetheless, something must be different about it on the new machine.
I'm guessing that this is some sort of permission issue, because I'm noticing that I get asked for the root password more frequently during software installs, etc., than I used to get asked on the old machine.
Can anyone suggest how I can diagnose this apparent permission problem and, of course, how I can fix it?

I have here a mac mini 4,1 that keeps losing it's Ethernet connection. If the mac is shutdown and restarted there is no connection, however, if the mac is shutdown, all the cables pulled from the back and replaced then restarted it boots and the connection is back. It was reporting a very strange mac address starting with 00 which I've never seen before and I also had difficulty connecting to it via ARD as it would show in the scanner but not connect unless specifically connected via IP address. At first I thought it might be a system upgrade as it happen when we upgraded to 10.6.8 since then I've wiped it and installed 10.6.3 and still no luck.

I would like to partition my internal 750GB HD into two parts. One for Media, and one for the OS and applications.
Is this possible without data loss? If so How? Should I clone my Macbook, reinstal the OS, and partition, then move media into the partition?

I edited a video in FCP and exported it as a quicktime. The resulting file is a little over an hour, about 13gb in size, and has 14 chapters. The quicktime movie plays perfectly. When I build the DVD in iDVD it works perfectly. However, once it's burned I lose the audio in the middle of the 13th chapter until the end. I've deleted preferences, re-exported the quicktime, created new DVD projects, used an older template (I'm now using a version 7 template).... I'm not sure what's going on!

I use a Sony HDR-SR11 AVCHD handycam. I import my clips into FCE4 via the log and transfer window, using the Apple Intermediate Codec. I edit my video, but i dont know where to go from here! What is the best way to export this video without loss of quality? These videos would mainly go onto youtube, iDVD, or a memory drive. I do not have quicktime pro, so any modifications would have to be within FCE4.

(I'm not sure if this is the correct Forum page, if not then I apologise - I'm new to MacRumors today)
I have a new 27" desktop Mac with the latest software.
I'm trying to send a photo by email without any loss of image size or resolution.
I've tried three ways of doing this:-
- from within the IPHOTO page and clicking on email at bottom
- from within an email in MAIL and clicking on 'Attach' paperclip
- by dragging a photo from IPHOTOS into the mail message
No matter what I do the 2.0 MB photo is automatically reduced to 23 KB even though I click on 'Actual Size (Full Quality)'
There has to be something I'm doing wrong.

Yesterday I upgraded to the latest MacBook Pro (13 inch. 2.4 gig) and have a wifi connection issue. Whenever I start data transfer over wifi to my NAS, airport loses the connection after 2 minutes and obviously the transfer is discontinued. In a normal usage mode (Web browsing, mail and so forth) the thing works perfectly.
(This is my first mac, I tried to find topics related to that particular data transfer issue yet without success, sorry in case this is a well known issue).

Since iTunes 9 came out the improved Home Sharing features has been quite useful to me, but today when I re-formatted my computer I ran into some problems. Both computers are using Windows XP, one is connected via Ethernet and the other one--which I reformatted, let's call it Computer B--connects to the router wirelessly.
I have activated each computer for Home Sharing properly but from Computer B, I can't access Computer A's library. On Computer A, I can access Computer B's shared library and listen to music as normal, at least for a moment - after being connected to the library for a period of about two minutes, it will suddenly disconnect itself and the icon will disappear so I am unable to reconnect. It's strange how I can connect to the library perfectly and just out of nowhere it will disconnect.

I have an early 2008 15" MBP with a SuperDrive that I never use. Can I simply remove the drive to reduce weight?
Seems that I would drop about 0.4 pounds. Yes. I'm aware of the OptiBays, but I'm more interested in losing weight than adding storage.

I have a 24" iMac that has completely all of a sudden stopped wanting to connect to the internet. However, my Macbook, connected to the same ethernet cord or wireless network, works flawlessly and has no trouble. The iMac will find the wireless network...show full bars...then drop a bar....then another bar, then another, until only the smallest bar is available. It will transfer data but only for a few seconds until it wont work at all. Now the macbook, sitting right next to the imac will show full bars and stay that way. So i tried a ethernet cable to the iMac and it will not even pull up 1 single page, but the same cable connected to my Macbook will work flawlessly.

Been using my imac lately and I've noticed a drop in wi-fi signal. I checked iStat and it said that the airport card's temp was 62?CIs the high temperature linked to the loss in signal?

I recently applied an EFI firmware update to my MacBook Pro 15" (early 2011), which is currently running OSX 10.7.3. Coincidentally, my clock now loses several seconds per hour (in both sleep or screensaver mode), so after several hours, I lose about a minute. Of course, I could manually correct the clock via System Preferences' Date/Time synchronization. But I shouldn't be losing this much time.

There is a problem of a periodic signal loss. The reason for this is the password reset network settings in the airport. It happens randomly during sleep. The system log says only connect and disconnect from the network. What may be the reason?
