If and when you try to open a quarantined app, Gatekeeper checks it for known malware, validates the developer signature to make sure it hasn't been tampered with, makes sure it's allowed to run, for example matches your settings for App Store apps and/or known developer apps, and then double checks with you that you really want to run the app for the first time, that it's not trying to pull a fast one and autorun itself.

MacBook Air :: Jumping Cursor Came Back After 10.7.3 Upgrade

Feb 3, 2012

since the upgrade to 10.7.3 on my MacBook Air (4GB mem) I am facing the problem with the jumping cursor again. I had this a while ago when using a Logitech M510, switched then to a Magic Mouse which worked fine.
The cursor is not moving when I don't touch the mouse (I see some other people having that problem which is even more annoying) but when I move the mouse the cursor is following, then stopping, moving again etc.
Now, with 10.7.3, this problem came back, so I assume it's directly related to the upgrade. And I have it with both devices now, the Logitech and the Magic Mouse.

Aug 18, 2010

Problem: Was surfing on my Mac Mini when the cursor starts acting erratically, when I try to move it, either freezing or it jumps all over the screen. I have tried repairing permissions using disk utility, resetting the 'pram', used clamXav to scan for virus. starting in safe mode to repair permissions.

MacBook Pro :: Turned On - Screen Jumping

Jun 27, 2010

Macos App Keeps Jumping Device

I turned on the MBP today (Mid-2007 Santa Rosa) and everything was going fine- until the screen started to jump! Literally the whole display bounces constantly, revealing a white line at the top of the screen (as if trying to center the screen or something). This is on the LCD- haven't tested it on a monitor yet. I just had my logic board replaced about 4 months ago for a faulty 8600GT chip- I'm so hoping it's not that.

MacBook Pro :: Battery Jumping From 85 To 0 Percent Instantly

Mar 5, 2010

I have a 5-year-old PowerBook G4. I remember I changed the battery about a year or two ago, because when I used to take it to classes in college, and use it unplugged, my laptop would shut off in less than an hour (more like ~30 min) when it reaches ~30%. After I got a new battery, it went back to normal, and lasted much longer. In the past couple of days, I noticed that within about 5-10 minutes of using my PB unplugged, battery goes from 100% --> ~85%, and then all of a sudden shuts down.
When I plug it back in to a power supply, and it starts back up, it starts recharging from 0%... this seems a little extreme. I haven't noticed this problem because I almost have it plugged in these days, as I usually use it at home or at work where I have a power supply available, and I use it for a few hour period at a time. Does this seem purely like a battery problem?! (ie. it's just time for a new battery...)

MacBook Pro :: Brand New Battery Jumping All Over The Place?

Jul 4, 2010

I just got my brand new, 13' MacBook Pro on Friday night. Friday night and Saturday morning it was plugged in to get it all setup and all my files transferred. In the afternoon, I took it off the charger and it said i was going to get 5 hours of life, I researched a bit and found out how to calibrate the battery, which I did last night and plugged it in again this morning.
I'm now in a coffee shop, first time with my MacBook on battery since calibrating it, and the time its supposed to last, is jumping wildly. Right now its says 8:55, but 2 seconds ago it was 6:08, and in the last 5 minutes its jumped as low at 5:32, and as high as 9:13, oh I lied, it just jumped to 9:49 as I was typing this.I used coconut battery and it says 2 cycles and 5850 mAh, 4 weeks old.
Why is it jumping so much? I did the calibration according to Apple's guide. Waited for it to go to go into reserve and then sleep, and then left it for 8 hours while I slept, and when it restarted this morning it said '1%' battery. I don't know what the issue is. My old white macbook jumped but usually a matter of 5-10 minutes, not hours.

ITunes For Mac :: Songs On It Skipping / Jumping?

Aug 30, 2014

using MacBook Pro os x mavericks / I have had this issue a few times now, I have purchased new CDs and came home to import them to my iTunes library straight away. They import perfectly fine but as soon as they're finished importing to library, I go play the album and a few of the songs skip or jump (like when you play a scratched cd in a CD player) though the cds are not scratched.
I am using the external USB super drive to import as the MacBook has no cd slot built in, I thought maybe I was bumping or moving the super drive while the disk was importing and this may be effecting songs being imported properly so I deleted the albums and imported again making sure the external super drive was not moved but there is still 1 or 2 songs playing up.

IMac :: Stuttering During Video Playback - Magic Mouse Jumping Around

Nov 8, 2010

During video playback (itunes, vlc...) stutters every 50 seconds or so (no exact interval) and the video currently playing pauses for a few seconds, the audio however continues on. After the short pause it skips a few frames ahead. It doesn't seem like a big problem, yet it's very annoying while trying to enjoy a movie.
Also, I'm not sure if these issues are related, but every minute or so my magic mouse jumps around the screen for multiple seconds (not only during a film, all the time...). Also very annoying, as I work with Photoshop & Illustrator, meaning I do very precise work with my mouse.

MacBook Pro :: How To Fix Mouse And Key Cursor Lag

May 7, 2010

I'm switching over from Vista so still trying to get used to snow leopard. Couple of things that are bugging me:
1) The trackpad seems to lag slightly when I select text or re-position windows on the screen. What I mean is that when I double click and drag to select some text for example, when I lift my finger from the trackpad (which should end the select procedure) and move the cursor elsewhere, text selection still happens. The only way around this is to not touch the trackpad for about a second before I can move the mouse cursor elsewhere. Is there a way to get rid of this 1 second lag?
2) When I'm typing, and want to move the key cursor over my text, when holding down the arrow keys, the cursor still moves over text very slowly. Is there a way to speed this up?
