Keyboard disconnect after Mac sleeps

When I wake my Mac after it's been asleep, I am presented with the login screen. Normally, I type my password and login. But since a couple of weeks ago, my bluetooth keyboard doesn't work anymore. I have to hard poweroff the Mac, and then during startup, they keyboard works normally. The Mac is just dropping the keyboard... what gives?

Thanks for replying. To clarify a few details you asked about:
The Airport Express (v. 7.6.4) is connected via the Ethernet 1 port to a Power Mac running OSX 10.9.5 (Mavericks). The AP Express is in "Join a wireless network" mode, and it connects to a LAN consisting of a cable modem/router, and a few devices such as a "smart TV." There is no Apple Wireless router involved. The cable modem/router assigns IP addresses to all devices, with no apparent problem except for the Ethernet port/Airport Express.
I tried the Network Prefs option "Configure iPv4 Using DHCP with manual address" but that didn't change anything. I've also tried setting the Mac to "never sleep" mode, but that made no difference either. I don't know exactly what you mean by a static IP, but right now I'm trying ""Configure iPv4 Manually."
I don't know anything about "sleep" settings for an Ethernet port, but I'll study your macrumors link to see what I can learn.
Any other suggestions - much appreciated!

Internet Disconnecting after Mac sleeps?

Hi, my family connects to one wifi network that starts at a Time capsule, but we use an AirPort Express to extend the network connection to my iMac, but recently every time I sleep, shutdown, restart, etc. my computer, I can't connect to the wifi network.
Then, when I go to connect, I get a dialogue to type in the network password (which is normal). However, when I type in the password and click "Join," it tells me the that the connection failed, BUT i get connected anyway.
I know it seems complicated, so I'll put a picture up
I guess all I really need help with is to get it to remember me. please help! thanks!

Try the following, in order, until (hopefully) resolved:
1a. Delete Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Under "Preferred Networks," delete the network(s) you regularly use from the list.
1b. Delete AirPort Keychain Entries
Launch the "Keychain Access" application located in Applications/Utilties.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
1c. Add Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Add the preferred network(s) using the "+" button.
Restart or log out then back in.
2. Move System Configuration Files
(Note: You will have to reestablish your network connections settings.)
Go to /Library/Preferences
Move the SystemConfiguration folder to the desktop.
Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)

Mac Wi-Fi disconnects after in sleep mode or shut down

Whenever I shut down or sleep my iMac and log back in, the Wi-Fi is not connected. In Network Preferences, it states that the Mac has a self-assigned IP. When I complete Network Diagnostics two or three times, the Wi-Fi will connect. I am connected to Verizon and have an iMac Late 2012 OS 10.8.2.

Hi, this has worked for a few...
Though all of these steps may or may not be needed, I'm including them all.
Make a New Location, Using network locations in Mac OS X ...
http://support.apple.com/kb/HT2712
10.5, 10.6, 10.7 & 10.8…
System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.
10.5.x/10.6.x/10.7.x instructions...
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
If using Wifi/Airport...
Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.
For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
208.67.222.222
208.67.220.220
(There may be better or faster DNS numbers in your area, but these should be a good test).
Click OK.

Network disconnects after Mac mini is running for several hours but a reboot fixes it

i have updated my Mac mini to Yosemite but now it has a networking problem after running for several hours . Trying to open a webpage in Safari or chrome doesn't work, the remote site appears to disconnect. Mail is not downloaded and email already downloaded has no images when I display them. Interestingly DNS resolution is working nslookup finds the IP but telnet to a web site on port 80 gets an instant disconnect.
THe connection ion is wired into a hub and the ISP connection is fine from the other computers on our home network.
I am now rather perplexed how to fix this without constantly rebooting the Mac which just goes against the grain.

Hi loseph94,
Welcome to the Apple Support Communities!
I understand that issues with your computer running slowly can be frustrating. In this situation I would recommend reading over and using the information located in the attached article to help troubleshoot the issue.

APC "ups" loses comm after Mac sleeps.

I have installed a brand new UPS made by APC. Back-UPS RS 1500G. It was installed yesterday, said it had a 100% charge according to the icon in the menu bar. Today, just before work of course, it went through it's first power outage. I was out of power for 1.5 to 2 hours. During which time the menu bar never changed from 100% and I never got the warning "Your computer is now on UPS. Back up any work and shut down soon." or whatever it says exactly. So I unplugged the USB, waited a minute and plugged it back in. Now it's telling me to save my work and shut down soon, blah blah blah. And it's at 95% charge. it went all the way down to 70% charge while I was on it and what not. Then the power came back on. So i saw it move up about 84% charge. I left for work, thus the Mac went to sleep at my schedule time of 15 minutes after idle.
After 11 hours, come back from work. Wake up the Mac and it's still at 84% charge. Unplug the USB, wait a few seconds and plug it back in. Bam, it's now at 100%.
Any one else having the same problem? If so, I'll report it to Apple.

APC's software was not installed. That said, I uninstalled apcagent and rebooted. Results were the same: Energy Saver doesn't detect the UPS.
An earlier thread on this topic hints that this may very well be a Yosemite software bug: Yosemite doesn't detect my UPS
A user reports that a clean reinstall of Yosemite did not fix their problem.

Macbook Pro trackpad and keyboard freezes after attempting sleep mode

I bought this computer on April 2008. It has the latest OS X 10.5.6 and it did not accept the trackpad firmware. I tried to install and the software said "this computer does not need this update".
This has been happening a lot when I am using Skype while talking to someone with video and sound. The computer tries to go on sleep mode because I am not typing or touching it - it thinks I am away because I am just talking and watching the person on the other side.
I touch the computer to avoid getting on sleep mode and with that it freezes the trackpad and keyboard. I continue to listen and see the other person and they continue to see me and hear me, but I cannot move the "mouse" cursor on the screen or type anything. Neither can I force to quit anything. The only thing that works is to close the computer and open again, that forces the computer to go into sleep mode then I can make it wake up again by opening it and touching any key on the keyboard.
This have been interrupting Skype calls and a study I am conduting. I have to keep touching the computer trackpad to not let it sleep ever. I am concerned is something with the battery or maybe it needs some kind of firmware.
This is very recent, just started happening this week (March 2009). I have not added any new software or any hardware to the machine.
What can I do to make the trackpad and keyboard stop freezing when the computer tries to sleep?

this is in the wrong category. I added a new message to the right category: MacBook Pro but I don't know how to delete it from here.

No signal after mac sleeps

Yes, cryptic subject line, but I couldn't summarize the issue.
I'm using Logic Pro and at times I have to put the mac to sleep. On waking, Logic Pro fails to 'see' any signal, even though both Audio prefs in Logic and Sound prefs in Preferences are set to my A/D converter.
So I have to restart the mac to get it working again (and, no, repairing permissions doesn't fix the issue), which is highly inconvenient and ergonomically contentious.
Please advise.

How about just restarting coreaudio?
Open Logic Pro>Preferences>Audio>Devices>Coreaudio, change a buffer setting, change it back, now the Apply button becomes available. Click it, or simply dismiss the window. Either action will restart coreaudio within Logic, so (hopefully) no need to reboot.
BTW, the sleep function has always been iffy on Macs, the first time it ever worked for me without disrupting anything was on a Hackintosh... on Macs it often seems to screw up attached peripherals (disks, audio interfaces, MIDI controllers).

Keyboard disconnecting during iMac sleep..

This happened twice last night. iMac on sleep all day, then I used it briefly. Put it back to sleep, and a few minutes later, screen turned on with "keyboard connection lost" icon displayed.
My keyboard's battery power is currently at 20%. Could this be the reason?
Thanks for any insight!

It's possible. The only way you will know is if you use some fresh new batteries. Post in the Bluetooth forum area - http://discussions.apple.com/category.jspa?categoryID=145

All USB drives disconnect after upgrade and clean install of MAC OS X Mavericks

I first upgraded to Mavericks and noticed that my external USB dries would disconnect after MBP Retina Mid 2012 model was updated to Mavericks. These worked fine in all versions of Mac OS X before upgrade. So I did a clean install figured my machine would benifit from this anyway. This did NOT fix the problem.
Wouldn't be much of an issue but I use this macine as a media server with Plex and all the media is in one of the external USB 3.0 drives. All drives are from Seagate, and have found no info there. Guessing this is a bug that Apple needs to fix unless its a Seagate issue which I doubt.

If the tracks are recognized by your iPod (playable), search VersionTracker for "iPod". You'll find a number of utilities that can transfer your tracks and your playlists from your iPod back to your Mac.
If they're just on your iPod as data, then I'm not certain since I don't use a custom hierarchy, but you should be able to copy the folder back to your iTunes Music folder, turn off the "copy to iTunes library when adding to library" preference, and then use the Add To LIbrary command to get them recognized by iTunes. Again, though, I don't use a custom hierarchy, so you might want to ask that question as a new post, just to get additional opinions.
BTW, an iPod is not a reliable backup for your tracks. Too many situations can arise that would cause your iPod to need to be erased. I strongly recommend that you make backups, particularly of any tracks purchased from the iTunes Music Store or that would otherwise be difficult to replace, to CD, DVD, external hard drive, or other medium.

My wireless mouse disconnects after a long sleep, and only rebooting machine makes it come back.

My wireless mouse disconnects after a long sleep time, always overnight, and pushing buttons, replacing batteries, etc. doesn't wake it up again. I have to reboot the machine, sometimes losing data, in order to make it work again. I am kinda new to mac, so hopefully I am just missing something easy.

Maybe something here will help:

After mavericks updating ,i cant pair my wireless keyboard , plus my mac is logged out for logging in i need my keyboard back any help would be here? Ps: i dont have another keyboard

After mavericks updating ,i cant pair my wireless keyboard keyboard working but just not pairing , plus my mac is logged out for logging in to reach the preferences i need my keyboard back any help would be here? Ps: i dont have another keyboard to connect .

For the both of you.
Turn your Mac on, wait until the login screen appears.
Turn off your keyboard, wait several seconds. Hopefully a "Keyboard turned off" or "Keyboard disconnected" comes up. Then remove the batteries.
Turn the Mac off then turn it back on.
When it turns back on, it should say missing keyboard or something of the sort. Put the batteries back into the keyboard and turn it back on. Hopefully it should start talking again.
It sounds like you two have a Mac that doesn't have a built-in keyboard. So you could easily reset the SMC...

Keyboard does not function after mac mini goes idle

Hi. Interesting issue. New keyboard on my mac mini. Identification of keyboard (cheap Dynex) works fine. If I let mini go idle/screensaver, when it wakes up, it does not recognize the keyboard at all. Cannot manually force it to recognize either. Restart works like a charm and all is good until it goes idle again.
Anyone seen this? Any ideas?
Thanks.

I used a couple of cheapo PC oriented USB keyboards when I got my first Mac mini. They had issues where they would stop working after sleep, screen saver activation, or would start doing double key strokes, and other glitches. Honestly, if it's not an Apple keyboard or specifically made for the Mac, I've always had the keyboard develop issues at some point. I strongly suggest getting a proper Apple or made for Mac keyboard. It has solved all of my keyboard issues.

I can't be the only one with this issue. MacBook Pro Retina Late-2013 WiFi disconnects after waking up from sleep.

Did anyone buy a MacBook Pro Retina 13" from Best Buy this Black Friday?
I'm having an issue where the WiFi disconnects after the MacBook wakes from sleep but only after a couple of minutes.
Once the WiFi disconnects, I can't reconnect to the same network and sometimes it won't find nearby networks.
I have to turn off the WiFi and wait for at least 5 seconds before turning it back on for it to auto-reconnect to my home network.
If I wait less than 5 seconds, it will continue to attempt connection to the home network but won't connect.
I've tried reformatting and deleting my network configurations as well as resetting my modem, power cycling it, etc.
I am using 2Wire Gateway modem/router from AT&T on b/g network.
I've tried connecting to a friend's network under Time Warner Cable and the same issue occurs.
I exchanged the MacBook at a Best Buy for a brand unopened one (I hope) and the same exact thing happens with this new one.
Really, I can't be the only one with this issue. Unless in a 0.00001% chance I received two defective units in a row?
Please.. does anyone have a clue why this is happening?

You're definitely not the only one. I have the same issue. I spent 6 hours over multiple days on the phone with Apple support trying a variety of things (some of which are mentioned above), and none of them worked. They finally sent me a replacement laptop. I made sure to try it periodicaly as I was moving files and installing applications to see if I ran into it again and things seemed okay at first but now I am running into the same issue and it is terribly annoying. I've got 5 other devices that connect to the same router and I've never had this issue with any of them.
My router is a Linksys E2000. I haven't tried changing the router channel but I have tried to cnnecting to other networks in the building I live in and I have run into the same issue there.

I have an optical mouse that came with my Mac Pro plugged into the USB port on the keyboard. After a year of working normally, the trackball all of a sudden stopped scrolling down. It scrolls up just fine, but not down. Any thoughts?

Well
I tried all of the suggestions, sort of. I did not have alcohol wipes, but I did take alcohol and pour some ona white paper towel and then rolled the mouse touch ball aroound and that finally cleared up the problem. Just inverting it on paper did not do the reick, it needed some help with the alcohol. Of course the probelm is the debris that gets inside and it really needs to come out.
This is a huge problem for RIM devices users too.

Log in screen appear after Mac goes to sleep even if screen lock is turned off.

Log in screen appear after Mac goes to sleep even if screen lock is turned off. This happens usually but not always. Using Yosemite, 2 year old iMac. This has only started to occur recently and it happened in Mavericks also.

Howdy stkh,
You may want to check the General pane of the Security & Privacy System preferences to make sure that the Require password...after sleep or screen saver begins is not checked. See this article for reference -
OS X Yosemite: General pane of Security & Privacy preferences
Thanks for using Apple Support Communities.
Best,
