MacBook Pro :: USB Device Disabled From Too Much Power Draw / How To Re-enable
Jun 19, 2014
i 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.

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?

I need to 'draw' a 'top down' view plan of a room in my house.
I think I could use Microsoft Visio on my XP laptop, but I want to be able to do it on my iMac. Any suggestions of applications that will enable me to do this?

When I booted up my computer this morning, I realized that the volume icon in the menu bar was missing. I tried to adjust the volume with the keyboard, but an icon came up that makes it seem like it's locked. I went into System Preferences and under Sound, the computer doesn't seem to find the speakers for output or the internal microphone and line-in for input. Has anyone else had this problem?

I had a brainfart earlier, and cleaned my keyboard while my computer was in standby instead of turned off. The result is that by wiping off the keyboard, I hit a ton of keys, causing a lot of bad things to happen to the desktop.

I was testing the pwpolicy on a newly upgraded Yosemite. After rebooting, I found my local admin account was disabled.
I ran the pwpolicy on a non-server version of Yosemite and the only support article I could find is OS X Server (Yosemite): Global policies can lock out Admin accounts - Apple Support. I tried to follow the steps in the article to clear the account policies for local admin, but once I entered "/usr/bin/pwpolicy -n /Local/Default clearaccountpolicies", the system seemed hanging there and the local admin account was still disable.
Actually once I used launchctl to load the com.apple.opendirectoryd.plist, the system started to show signs not working properly, such as some basic commands like ps, dscl, man, nano, or even ls stopping to bring up any results. However, "launchctl list" showed the daemon was launched with a number of 78.
I tried to create new admin user account by rm /var/db/.AppleSetupDone, but the new admin account was disabled possibly immediately after birth because of the global policy settings.

I think I need it to play Yahoo games. I went to Safari Preferences and checked Enable Java. (Enable JavaScript was already checked.) But when I click on a Yahoo game, the page loads, yet the game doesn’t appear. I thought I could just enable Java when I wanted to play, then disable it when I wasn't. Obviously this isn’t urgent, but if there’s an easy and safe way to play, I’d like to know.

I've got another ongoing thread (2006 Mac Pro Elevated CPU Temps) where I've been attempting to determine why my 2006 Mac Pro was running so much warmer than I recall at time of purchase By sheer luck, I seem to have stumbled on the cause... when I first noticed it, I was running 10.5.7 with the CPUs idling around 130F or so... as noted in that thread, I tried all sorts of things such as cleaning the dust out, reapplying the thermal paste, etc... all of which had no impact... for an unrelated issue, I decided to re-install OS X 10.5 base version and I was shocked to discover my CPU temps back down in the mid-90s F

I have an 14" iBook, 1.07 GHz and it won't use battery power. As soon as I unplug it it turns off. It worked fine until I opened it up and swapped in a DVD-RW and a new hard drive (the old one was failing). In the power section of system profiler it shows 98 load cycles and about a 75% remaining capacity. It may or may not be charging - I can't tell. The battery says it's fully charged at 95% and I have no way to drain it and see if it will recharge because the computer won't drink from the battery. I had another 14" iBook battery laying around that I thought worked, but now when I put it in this computer it just sits at 0% then eventually says the battery is dead (the menu icon shows an X through it).

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.
