New 'Sleep Display' in Leopard

New to Leopard, the "Hot Corners" options in Screensaver prefs now includes the ability to set one or more screen corners to "Sleep Display" to make the energy saver kick in. Is anyone using this? Is anyone having problems with it?
I have dual displays (23" on a Mac Pro) and, of course, going to the corner I have designated to "Sleep Display" turns off the backlight in both displays. Oftentimes, when I come back later, the displays cannot be re-awakened. If they can, often the entire system is unresponsive -- no cursor/mouse movement, even the menubar clock is frozen.
There are two, separate failure modes: 1) when I move the mouse, the display awakens to show the system unresponsive and the clock shows a time around when I slept the display. The system is unresponsive to mouse clicks and keyboard input, though the mouse cursor is able to be moved; and 2) the displays do not awaken and I can sometimes log in via ssh to see that the system seems to be operating just fine (as determined by active processes in 'top' and the system date/time being current.)
Do any of you experience anything like this or have troubleshooting advice for someone who is?
I did not have this problem prior to upgrading to Leopard.

Bump. Same problem here. Just started though... I've had Leopard for months with no problems until now.

How do I transfer files from mac with snow leopard to a new retina display mac

What is the easiest way to transfer files from my old mac(2008) snow leopard to my new retina display mac book pro?

Easiest? Well there is some sort of wireless transfer thing, but I hear it takes FOREVER like several days and it's glitchy.
The Retina doesn't have a Firewire port I believe, so Target Disk Mode is out, unless you have a adapter and I don't know how well that will work out. Cost another $30 for the adpatper I bet.
The likely most easiest?
Run down to any computer or office store and pickup a powered external USB hard drive that's the same size or larger then the old Mac's boot drive.
Boot the old Mac and download Carbon Copy Cloner.
(or use the TimeMachine if it asks, but it takes a reallly long time and if there are problems, then it's harder to recover files from)
Format the external drive in Disk Utility with Partition: option GUID and OS X Extended Journaled (default setting)
Use CCC to clone OLD A boot drive to External Drive B, takes about a few hours depending how much stuff you have.
Hook up drive to new Mac, (either clone or TimeMachine drive)
Use the free Migration Assistant in your Application Utility folder to transfer over, but creates a new user account (you can later delete one)
Or if you haven't set up the new Mac yet, when you do set it up during that process, you can transfer from the External Drive B and it won't have the account you set the machine up with naturally just uses the ones from the clone or TimeMachine drive.
Once your fine and dandy on the new machine, then Disk Utility erase and use the external USB to create either a bootable clone with CCC or a TimeMachine drive for backup.
Since you need a backup drive anyway, this method is better and happens to be reliable and easy.

Sleep Display not staying asleep when encoding video

Hello,
I am looking for a way to turn the display off and KEEP it off with applications running as normal, until I want to wake it up. It is not always staying asleep.
I have a hot corner set up so that I can instantly turn my iMac display off (including the backlight). This works fine most of the time, but when running certain applications, activating sleep display works for a few seconds then stops working and the screen comes back to life.
Example applications which cause this are iTunes when encoding a video (e.g. converting a movie to iPod format), iSquint when encoding video, iDVD when encoding and burning a DVD - seems to be anything that makes heavy use of the processor.
I have tried all sorts of things to get around this:
1. setting the sleep display timer to 1 minute in the Energy Saving settings
2. 3rd party application and widget "Sleep Display" (http://linestreet.googlepages.com/home) which claims to make the display go to sleep and STAY asleep, suggesting "This version may work for people who experienced the monitor going off then coming right back on" - which indicates that it's not just me having the problem. This "Sleep Display" application doesn't work with Leopard though; the author acknowledges this and suggests he will update it if he upgrades to 10.5
3. different application - http://www.imalc.com/Site/SleepDisplay.html - this does the same as the hot corner and wakes up within a few seconds
4. sleep display tool in Dockables - same problem
5. "shades" system preference add-on, this makes the screen black and keeps it black but doesn't turn the backlight off
6. tried hiding the offending application, moving it to another space - nothing seems to work!
7. covering the imac with clothes - not ideal!
Thanks for your help!
Jim
P.S. the screensaver does stay on - so whatever is waking the sleep display isn't disturbing the screen saver - this suggests to me it's a bug. Obviously a black screensaver isn't the solution though - the backlight is still on.

I've got a very the similar problem. Brand new iMac 24" that shipped with Leopard -- my first Mac after jumping ship fom the Windoze side.
I had iTunes updating it's album artwork and since it was taking a while, I went to bed. When I turned out my light, I realized the screen had not yet gone to sleep (a good 15 minutes after it should have). So I set up a Hot Corner to put the display to sleep. When I put the mouse there, the monitor would go to sleep, but wake up within 10 seconds. At first I thought it was just the mouse moving as I walked away, but it wasn't.
I ended up turning the computer off because the big beautiful screen was throwing too much light. Since, I rarely turn my computers off and they're usually doing SOMETHING, this is really annoying.
Admittedly, I haven't tried some othe the potential solutions above, but this has to be the same bug. Screen saver stays on, monitor comes out of sleep.
Any help would be.....well.....helpful.

Sleep Display Option in 10.4?

Hello Discussions,
Does anyone know if the 'Sleep Display' option available in Exposé in OSX Leopard is available for Tiger?
Perhaps a script or third-party piece of software?
Thanks for any advice.
Cheers, R.

Thanks Dale,
A little mis-understanding here
Yes I know that the Energy Saver can sleep the display, however, this is after a period of time.
In Leopard, you can sleep the display immediately as an option in Expose, which seems to be absent in Tiger.
I was hoping there was a workaround for it.

Brand new Thunderbolt display shuts off randomly

I've had a new ThunderBolt Display for less than a month paired with a brand-new Mac Mini (2.6 GHz Intel Core i7, 16 GB 1600 MHz DDR3, Intel HD Graphics 4000)
and the display just began shutting off randomly.
I also have an external HD drive daisy chained via the display's Thunderbolt port that stops working once the display dies. Tried connecting the Mac Mini alone with no hard drive figuring it might be the drive but no the display still randomly shuts off. Any ideas or suggestions before I call Applecare?

I have a similar setup and problem. My Thunderbolt display (refurb, purchased in February 2012) will randomly turn off, as if it went to sleep - but mouse/keyboard input does not wake it back up. The internal speakers will still output audio. Disconnecting/reconnecting the Thunderbolt cable from the attached Mac Mini (2.5GHz dual-core Intel Core i5, OS X 10.7.5, AMD Radeon HD 6630M ) will not resolve the issue. Disconnecting/reconnecting the display's power cord and the Thunderbolt cable from the Mac Mini will resolve the issue temporarily. This began happening maybe a month or two ago, and has probably happened 10 times in the last 30 days. It is completely random, and I have yet to be able to duplicate it on demand.
Steps taken to attempt to fix the issue:
Confirmed Energy Saver Settings
Confirmed Software up to date (OS 10.7.5)
Attempted Firmware Updates (message states not needed)
Reset NVRAM
Reset SMC (unplugging computer)

As well as other discussions concerning random flickering issues with the display.
Since I'm still under warranty, I took my display to a Genius Bar today. The rep didn't really seem to want to hear about what I found on these discussion boards. He says you can pretty much find anything you want to find here, and since it is unmoderated it is not a reliable source of information. I let him know that the issue (as far as I can tell) occurs with different models of Mac Mini's, MB Pros & MB Airs, suggesting it is in fact an issue with the display and not what's connected to it. I added that most folks who reported bringing the displays in for service ultimately ended up with a replacement display, as the service done on the defective display proved to not resolve the issue - but I would of course defer to his judgement.
He decided that they would order and replace the LCD panel. He assured me they would keep the display powered on for 12-24 hours after the service to ensure the issue has been resolved. Truthfully, I am not optimistic. And for the amount it costs to replace the panel ($833.32 from the provided estimate), I speculate this course of action will end up being much more costly for them in the long run. But we shall see!
I will be sure to provide updates as they come. Wish me luck!

I am going to buy myself a MacBook Pro in the near future and was wondering if the new Retina Display model would be worth the extra cash. I will mostly be doing photo/video/music editing.

if you're not in a big rush - why not hold off until Adobe and Microsoft releases an update to support the Retina Screen.
Don't get me wrong - the Macbook Retina is a good and videos look great - but when it comes to Photoshop, it's a little blurry and the fonts in Excel and Word is pretty blurry too.....I own one....
In any event, if it's something you can live with - then by all means - go for it.....
Otherwise - get the non Retina Macbook Pro - it's cheaper, and it's user upgradeable in both RAM and Hard Drive.
Good luck.

HOW DO I INSTALL DISK OF NEW 10.6 SNOW LEOPARD ? NEW MAC DO NOT HAVE DVD ACCESS . BUT I WORK ON OLD MAC 10.4. TIGER THAT DO HAVE DVD PLAYER . I KNOW THAT SHOULD BE EAZY . THANKS

You'll need to provide some more information .... what current mac mini do you have? Click on the apple in the left corner of the menu bar, click about this mac, and what does it say for processor, memory, and os x version?
When you say you have no DVD, do you have the mac mini server or is the DVD broken?
You can't do anything with 10.6 Snow Leopard on a PowerPC mini, however, if it is an Intel-based mini, you could probably hook up the systems in target disk mode to install 10.6.

I just bought a new Retina Display macbook pro, and I plugged in my iPod touch (4th gen) into the new computer, but it will not show up, even after I typed in the passcode. How do I get my iTouch to sync with my new computer without restoring my itouch?

Anyway to upgrade my 09 macbook pro with the new mini display port that supports both audio and video instead of just video?

If you are referring to Thunderbolt, no.

Can I connect my thunderbolt display's power cable to supply power to the new retina display macbook pro?

I'm planning to buy a new retina display macbook pro, but I have a thunderbolt display and I use the display's power cable to supply the power to a macbook air. As the power connector on the new macbook pro is differet, It looks to me that I won't be able to connect it to the new computer. I'm I correct?

You'll just need this adapter, which you can buy or order with the computer:

Why can't I post a new topic in the Leopard discussions.

The option is available in other Apple discussions, but for some reason it's not an option for me in the Leopard area.
I just want to ask a simple question about why Firefox is now launching every time I restart my computer, but don't want to do so in a discussion about Final Cut or iLife or any of the other forums where posting a new topic is an option because that would be bad etiquette. At the same time, I'm not given much of an option.

Sony e reader prs 600 not showing in bookmark pane on my new Mac with Snow Leopard

I have a brand new sony e reader prs 600 it is supported but I am unable to see it on the bookmark pane in my new Mac with Snow Leopard is it something to do with Snow leopard? Or why can I not see my sony e reader? thank you

According to the Adobe website ADE 1.7.1 is compatible with Mac if you
look at system requirements and with the Sony reader if you look at
supported devices. Though it doesn't mention Macs latest O/S.
and if I download an Adobe digital editions book, can I then move it
to Sony's ebook software, or is the format unsupported on the Sony
Ereader?

Have new Apple Display Monitor

I have a new Apple Display Monitor with new Thunderbolt cable. I currently have a MacBook Pro with older Mini DVI port. Is there an adapter for going from TB to DVI?

No - you MUST have a Thunderbolt port on your Mac in order to work with the Apple Thunderbolt Display.
Sorry,

New Cinema Displays on an (old) G4-867???

Hi. I have a PPCG4 867 MHz (OS 10.4.8, 512MB RAM) with factory installed NVIDIA GeForce2 MX with TwinView display card. I'd like to upgrade to a new cinema display, either a single 23" or dual 20" setup. I do not do heavy graphics or gaming, but just would like a bit more screen real estate. Three questions:
1) Will my current system support the 23" as a simple plugnplay?
2) Will my current system support the dual 20" as a simple plugnplay (I'm not sure what the nomenclature "TwinView" implies), or do I need to purchase a different graphics card? If the latter, any specific suggestions?
3) Any other ideas that I should consider?
Thank you!

Yes, if you have done the firmware update

For the new 23" you will need the ADC to DVI adapter

simple plugnplay (I'm not sure what the nomenclature

different graphics card? If the latter, any specific
suggestions?
No. Your card has one digital (ADC) and one analog (VGA) port. Apple displays are digital only. "TwinView" means both ports can be used at the same time. You would need a graphics card with two digital ports to run two 20" Apple displays. There are no new cards suitable for your G4 (the ATI Radeon 9600 Pro PC/Mac Edition 256MB does not work in many older G4s). You may be able to find a used board, such as the NVIDIA GeForce 4 MX Ti, or get a non-Apple display with a VGA input.
