I'm putting a computer in my kitchen that anybody in the house can use (kids & parents). It will be hooked up to a 24" LCD and also act as a small file server, dvd player and perhaps eyetv dvr.
I like the mini because it is small (can hide in the cabinet where spills won't get it), is cheap and uses only 13W when idle. But when I think down the road, 4 year old laptops seem a lot more useful than 4 year old mac minis. So I'm a bit torn.
So my questions are:
- Does anybody know how much power the macbook uses when "idle" (just running finder).
- Can the macbook be run with the lid closed? (I know old powerbooks used to vent hot air through the keyboard.)
(Then again, I have the computer in the kitchen so I can watch my kids on the computer. In 4 years they'll be 5 years old and probably want a laptop they could have in their own room - exactly what I want to avoid. And I'll probably upgrade my macbook pro by then anyway.)
Today my mouse ran out of batteries, so I went to get some new ones. I replaced them, the light on my mouse went on, and it seemed to be working. But, when I tried to move my clicker thing *on the computer* with my mouse, it didn't move. So, I looked at the bluetooth symbol on my computer, I'm on a MacBook, and it showed that my mouse wasn't connected. So I tried turning off the bluetooth, shutting off my mouse and turning it back on, taking out and putting the batteries back in the mouse, and none of these worked. So I went to "Browse Device" and my mouse was there, I clicked on it twice and it said "There was an error connecting to the device". I also deleted it from the bluetooth list, and I am now unable to get it back on the list!
View 1 Replies View Relatedi just recently got a keyboard i had back and plugged it in with a mouse i typically use all the time. when the keyboard was plugged in i got the typical message for "USB device drawing too much power, has been disabled…" i just want to re enable the mouse. it was quite obvious it was the combination of BOTH devices that caused this, but i'd really like to just get the mouse working again. I've Tried Resetting the SMC and ran the diagnostic but nothing has worked.

I'm receiving the "no boot-able device insert boot disk and press any key" error every time I go to turn on my macbook air. The screen chimes, turns on and then goes black. I've been holding down the option key and that seems to work but do I have to do this every time I turn my computer on from now on?

I have a total of 10 USB devices connected to my G5 Mac, including hubs, printers and scanners. Most behave fine, but one or two cause minor problems. The worst offender is a Sierra Wireless 875U Aircard, which is a wireless broadband modem I got through AT&T. I use it for my Internet connection.
Every time I power up my Mac or bring it out of sleep, it won't recognize the 875U, even though it's plugged directly into the Mac's front panel USB port. I can't even see it on System Profiler. Having it in a different port or going to a hub port doesn't make any difference.
To make it work, I have to unplug it, wait a few seconds and plug it back in. My Mac then recognizes it and it works fine until I shut down the Mac or put it to sleep again. Granted, this is only a nuisance level problem, but it would be nice if the Mac recognized all the ports all the time. I'm running a duel G5 2.0 GHz under Mac OS 10.4.10. I see the exact same problem in my G4 iBook (1.0 GHz) also running Mac OS 10.4.10.

I hope the following problem is not too long winded. we have 3 identical Dual 1.8Ghz G5 Power Macs all with 30" Apple LCD screens, when any usb storage device is connected powered or unpowered, memory stick or hard drive, any pictures copied over to the mac are corrupt (lines through them, half the picture sheared off to the left or right, half the pic in another colour etc). f i connect the device to one of our older G4 machines or one of our new imac's there is no problem.

Just recently, I keep receiving an error, every couple of minutes or so, thats states: "A USB device is currently drawing too much power. The hub to which it is attached to will be deactivated." Now I have seen this same problem posted, but I have No Device hooked up at all. I have a 2 year old macbook pro 2.4 GHz, running 10.5 I've tried rebooting but it continues to occur.
View 3 Replies View RelatedI first installed Windows XP when I got my early 2008 Mac Pro. Boot Camp was probably beta back then, but I cant say my experience has changed much through Vista 32 bit or now Windows 7 64 bit. The way to dual boot, holding ALt during boot, has worked 1/10 times. Literally. The boot symbols are usually delayed, so I know when I choose the win partition, it gives me the "No bootable device" error. Two times have I had heavy OS X crashes after these boot-up "games". This last time I had to completely reinstall OS X (or upgrade to SL). How could this be, im not even booting into OS X when I am trying to boot into win.
I even have a separate hard drive for my Win partition. Not to mention the stream of driver issues you encounter when you finally manage to get inside Windows. I actually had my apple wireless and mouse working in Windows 7, but then I installed Boot Camp drivers of the DVD, and now theyre dead. I know. Its Windows, why would I miss it? Gaming or apps, regardless. Apple shouldnt include a program that functions so poorly, if they insist on higher standards elsewhere. It only reflects badly upon them. I consider myself a decent level mac user, venturing into command line troubleshooting if needed. But BootCamp remains a mystery to me.

I am trying to connect a Macbook Pro to my printer wirelessly. I can connect it, but it uses my other Macbook Pro as a server (shared). I cannot connect this printer to the previously mentioned Macbook directly, as I get the message; "an error occurred while trying to add the selected device. Unable to communicate with the printer at this time."
On the printer selection menu, it says the printers are "bonjour printers". The shared printer via my other Macbook shows as shared, and the (same) printer directly off my network does not show shared, so I think it is a sharing problem.All the printer sharing is enabled, so I don't know why it shows that it is not shared.
The printer is a Canon MP530 which works fine. Everything connected fine before I used this printer. I am running Yosemite OS X 10.101 on both Macs, but I don't think that matters because I had the same problem before I upgraded. I have reset the printing system, repaired permissions, everything I can think of, and I still can't directly connect this printer over wi-fi.The driver even upgraded with the new OS X, so it's not the driver.
I can print, but only using my other Mac as a "server", and it has to be on. I shouldn't have to do that.The main question seems to be how do I set sharing permissions when they are already set to share?These are my choices on the "add printer" menu:
-PS-736C74-U1 (Bonjour) (does not work)
-PS-736C74-U1 @ user's MacBook Pro (Bonjour shared) (works!)

This is a problem that's been bugging me now for a while: when I plug in my iPhone or even a measly Usb Flash drive into my Apple Keyboard's USB port, a message appears on my Mac's screen saying: "A USB device can't draw enough power to operate properly. If the device came with a power cord, plug it into an electrical outlet. Otherwise, connect the device to a USB port on your computer." Does anyone know why the Apple Keyboard has a weird indented USB connector?
View 3 Replies View RelatedI get this strange message every so often, sometimes more often than other times. It says:
USB port drawing too much power. The device that is plugged into it will be deactivated.
There are only two things plugged into the USB-The keyboard and mouse. When I get this message, the mouse freezes. If I jiggle the mouse cable where it is plugged into the USB, it comes back and everything is fine until this message comes up again.
I was looking through the posts on here and the only solution I could find was to reinstall Lion, so I did, but it still doesn't work. Everytime I plug the mic in it says, "USB device requires too much power." I just bought the mic. I tried calling the Blue mic costumer service but no one answers.
View 2 Replies View RelatedI have an 13" MBP that I ordered new in April, 2012. It is running Lion. I have an external monitor that is capable of 1440x900 resolution. I have an external keyboard and trackpad hooked up, and I like to close my MBP up and stick it in a BookArc. I want to be able to have the internal display disabled and to have the MBP only allow me to put windows on the external display, so long as the lid is closed. I also want to be sure that I am taking advantage of the resolutions available on my external monitor, which are higher than those supported by the internal display (specifically 1440x900).
This doesn't seem to work because I either have to allow the MBP to continue to draw my desktop across both screens (internal and external), OR use the "mirror displays" mode, which restricts my resolution of my external monitor. This means I either forgoe the additional resolution benefits of my external monitor, or I end up with windows that fall off-the-cliff, so to speak, because they are drawn in the portion of the desktop that would be shown on my internal display (which is closed).
I've read the community support pages on using the MBP with an external monitor, most relevantly, this page. It simply recommends using the "mirror displays" option. However, this option, as I mentioned above, doesn't allow me to make use of the additional resolution, and my external display looks bad. how to keep the 13" MBP in closed clamshell position, with the internal display disabled, and use my external monitor at resolutions higher than those allowed by the 13" MBP but which are available to my external monitor when not in "mirror displays" mode?

I am wondering that is it essential to connect power adaptor all the time while operating in closed calmshell mode? When I unpluged the cable it didn't work. Is there some way?

When I sync my iPhone and iPod with iTunes, I get an error that says some obscure video can't be synced because the device doesn't support the file. I've included a picture, and have searched for the file, but can't find it! I would delete it if I could find it.
