I installed Yosemite 10.10.1 on my iMac and my monitor keeps going to sleep while I am using it. I need to push the power button to turn it back on. And sometimes I have to hold the power button down to restart it and reboot the machine.

I picked up a new MacBook yesterday and I noticed a weird issue when coming out of "monitor sleep" mode, not regular sleep mode.
When I move the mouse, the external monitor shows what you see in the picture, kinda like a TV with no signal. The MacBook screen works fine so what I just do is unplug and re-plug in the DVI plug and everything is good again.
My 24 inch Dell monitor worked fine with my M1330 and other computers so I know it's not that. Does anyone have the same issue or maybe give me some light on this?
I just got my Mac Mini and have been setting everything up. So far no problems. However, when I inserted the installation cd for my monitor, it won't autorun. The cd shows up on the desktop, but I can just open it and read the files - can't run it. The cd seems to be a hybrid.

I previously used Appzapper and AppCleaner but they do not truly find everything. Is there a way to run an installer through a program that will monitor any changes it makes and output it to a log file?

I have an old MacBook6,1 of 2009 (the white one), with a 2.26GHz Intel Core 2 Duo processor, 2GB 1067 MHz DDR3 memory, 250GB of storage capability (100GB free), currently running Snow Leopard 10.6.8.
I'm trying to upgrade to Yosemite 10.10 (my hardware and software are both ok to do the upgrade, I checked it). The download from the appstore went ok, but when I launch the installation app and I am asked to select the volume in which I want to install the OS, I'm not able to select my "Macintosh HD" unity (the icon is light grey), and if I try to click on it anyway, a message appears: "Impossible to use this volume to start the computer" (actually my mac is in italian so I reported the translation of the original message: "Impossibile utilizzare questo disco per avviare il computer").Â
I found out that some people had the same problem with the installation of Lion (OS X Lion: il programma di installazione indica "Impossibile utilizzare questo disco per avviare il computer" - Supporto…), but all the proposed solutions rely on the possibility of accessing "recovery mode", a functionality that is not enabled in snow leopard 10.6.8. And the only solution that doesn't rely on this feature (you can find it at the same link reported above), requests a redimensioning of the partition assigned to "Macintosh HD", that in my case is the only one that I have (I don't have any bootcamp partition), and even if l do it, it doesn't work.Â

My iMac refuses to sleep no matter what sleep preferences I set or even if I try to sleep it manually (apple>sleep). It doesn't do anything. The display doesn't even dim like it used to a week ago. I don't have anything plugged in but the keyboard and regular mighty mouse, and restart doesn't change anything either. The Apple store installed a new hard drive on the computer a few days ago, since the 1.5 year old one randomly crashed and died. So I don't know what kind of funky things they might have changed, I'm just wondering if there's any simple maneuver I can do to make it sleep like it's supposed to!

View 3 Replies View RelatedI recently upgraded my OS with the free installation for Yosemite. When trying installing Yosemite my Macbook Pro running Mavericks asked me for the user password, which I provided.Yosemite installed fine, no problems.Â
Now, however, I am needing to install some software on my Macbook Pro after installing Yosemite. Like before, it asked me for my password, but this time it came back as incorrect. I tried several more times and it's still registering as incorrect.
I followed the directions shown here: OS X Yosemite: Reset a login passwordÂ
However, I can't follow the instructions past step 4:
4. Choose Apple menu > System Preferences, then click Users & Groups.
5. Log in to your account....
When I click on Users & Groups, I don't see anything that allows me to log in to my account (I'm assuming it's because I'm already logged into it?). I only see options to Change the Password, open the Contacts Card, Login Options, and change Parental Controls. When I select "Change the Password", it asks me to enter the old password, which I can't do for obvious reasons.
So what can I do to recover my existing password?

I just installed Aperture 3.6 in Yosemite on my new Mac - after the installation I agreed to use one library for iPhoto and Aperture - next the installation appears to have imported over 3000 program / Resource images and stored them in my Iphoto librarys and projects and in Aperture? The images look like thumbnails to low resolution clip art and some date back to 2006.

I'm using an Envision 17" LCD with a Mac Book Pro, also have an Apple DVI-VGA converter in the mix. I know this monitor works fine with this computer but suddenly, I'm getting no signal.
Power cycling the monitor doesn't work; unplugging/replugging the video cable doesn't work.Â
Rebooting works, but if I try to change the resolution, the monitor stops getting signal. I know the computer "knows" the correct rez, but doesn't always offer it. I suspect a corrupt software component...Â
This monitor/cable works just fine with my 2009 MProÂ

After upgrading my MacBook Pro 13-inch (mid-2010) with 8 GB of RAM to Yosemite (10.10.1), the monitor streaks on and off (almost like it's an old dot matrix printer). I've repaired the permissions and the disk, but that didn't work. how I can get the monitor to stop flashing?

my computer doesn't turn off its monitor any more. i check the energy saver preferences, and its the same that i've had them before. the screen doesn't even dim anymore.
View 3 Replies View RelatedMaybe this is a dumb question, but it seems on my system if the screensaver runs then the monitor sleeps, the screensaver is still running when i go to wake the monitor. does that mean its been running the whole time wasting cpu cycles and drawing more power than is necessary? you'd think it would stop.
View 1 Replies View Relatedhave a (late 2008) unibody Macbook Pro connected to an external monitor via mini-displayport to HDMI. The MBP is closed and the external monitor is my only display. I have a USB hub connected to the MBP which is connected to a mouse, keyboard, external HDD, etc.My problem is, the computer won't go to sleep unless I manually select the option from the menu. In the Energy Saver settings, the monitor and computer are both set to go to sleep at 15 and 20 minutes, respectively, and the monitor goes to sleep just fine. The computer never does, as indicated by the solid white indicator light on the front of the MBP and the fact that it stays warm after not being used for hours.

I am running an adaptor to my G5 from the ADC monitor (DVI to ADC).The screen usually runs fine when I reset the monitor or turn it off but as for when I put it to sleep, no such luck..This has happened once before and last time I just waited and randomly turned it on a couple days later and boom, the screen booted up.I have tried basic options, like resetting the computer several times, pulling the power cable out of the G5 for several minutes and even a PRAM reset but nothing seems to have made it work as of yet.I assume it's within the G5 as it has happened a few times and the monitor works fine when I test it on other computers..Also as I mentioned before this is not the first time it occured and it just randomly seems to come on whenever.

I was wondering if there was anyway that I could get my Dell E173FP monitor to sleep when I close the lid to my macbook pro. I do not have it on mirroring mode. When I close the lid to my laptop it will just switch my desktop to the monitor instead of the monitor going to sleep with my macbook. When I press the power button and click sleep or go to the apple menu and click sleep it will work though. This really irritates me and I would like It to sleep when I close the lid instead of having to do more.

Often when I put my iMac to sleep in the evening I find the system unresponsive when I come to use it the next day. I can see instantly that the system has an issue because I see that the screen backlight is on. The system does not react to any mouse or keyboard input and requires a power off reset to restart.Â
I thought that the issue may involve Parallels which is often running when I have this issue , however, I have spoken with Parallels support who recommended removing parallels, repairing the disk permissions and reinstalling Parallels which appears to have had no effect.Â

To figure our what is going on I've started OSX in safe mode and logged in using the guest account. Also I've turned off WIFI and Bluetooth. The problem still occurs. The syslog shows relatively little from the moment that I select 'Sleep' and the computer wakes again (see below).

After a recent upgrade to Yosemite my dual monitors randomly don't awake after sleep. This all worked fine in Mavericks.Â
(I have a similar problem with my Thunderbolt disk drives which again worked fine in Mavericks, but now I always get "Disk did not eject properly" on awakening from sleep. I'll post this as a separate issue.)Â
The manual solution to both problems is to unplug the Thunderbolt cable - but doing that more than 10 times a day is not on.Â
