User has a Macbook Pro that will only attach to a single access point in the building and will not roam from one access point to another.  There are 1700 devices that work just fine and are very mobile.  This device drops the connection and shows that WIFI is on but not connected.  Attempts to connect pops up the connection and asks for a password but will not accept it with an error invalid password.  I have tested it as well in other buildings which all use the same wireless access SSID and pw.  It will connect to the first access point it finds in the building but will not roam to another.  

I updated the OS to High Sierra to see if that would make a difference but the results have been the same.
Hi all - I have a small office network ... 1 room, 2 computers (Macs), 2 printers, and an IPhone.
All connected via Fiber Modem (Arris NVG595) & separate WiFi router (ASUS TM-AC-1900).
For the past several months, I have been pulling my hair out, with printers "sometimes" seen my the Mac, Airplay printer "sometimes" being seen by the iPhone, etc.
Fortunately, I have the issue narrowed down to this (assuming this is the cause):
When one of my Macs/Ptrs is connected to the LAN via Ethernet, it uses the internal IP of 192.168.7.xxx
When one of my Macs/Ptrs is connected to the LAN via Wireless, it uses the internal IP of 192.168.29.xxx
(FWIW I only use band 2.4GHz. I have nothing using band 5.0 GHz).
Can anyone direct me from here? Do I need to have everything on the same subnet?
Hi all - Will try to explain carefully ... thanks for reading ...  

My problem:
I am experiencing intermittent issues when watching a movie, which is a 7GB file on a local network drive of mine. Downstairs all works fine. Upstairs, when the issue occurs, the movie will play for 10 seconds, then I get a wait-icon (hourglass or what have you) for about 10 second, back & forth over & over.
Sometimes it behaves this way, and other times is perfect.

My Network:
Fast Ethernet service (Time Warner) from the street into my Modem. All over Downstairs it clocks at 110 Mb download and 13 Mb upload, using speedtest.net.
UPSTAIRS I have an Apple Airport Express, setup as a Bridge "Extend an existing network", which worked fine downstairs until I moved it upstairs.  Then connected to that is an Apple TV connected wirelessly, using the same netwk name (SSID).  It clocks at 30 Mb down & 8Mb up, way slower than Downstairs, but I thought would still be fast enough to watch a movie without speed issues.

Note that the data/movie is coming over my LAN ... that I have saved on a local network drive in my house. It is *not* being streamed from any services!  The 7GB Movie is on an ext hard drive plugged directly into the Airport Extreme Base Station.

Can anyone suggest how to troubleshoot this? It's been a long time since I broke a perfectly working network and had to do this!  I am thinking:
- Get a meter or Util to measure exact bandwidth/signal strength?
- Change to use …
I have a Mac that died when its video card failed. There is no way to fix that that I have found yet.

If I buy a new Mac, I know I can access the hard disk from my new Mac. Is there a way to access the CD Drive of the old PC from the new PC also?

I have 3 Macbook Pro's in the same location, along with 2 Windows PC's.
One of the Macbook Pro's ... just one ... is significantly slower at moving data ... meaning both for Upload/Download speeds over the internet,  as well as moving data files around internally with my LAN. By 'significantly' I mean it moves info about 10-15% of the speed of the other Mac's & PC's. (I measured with speedtest.net and a stopwatch!)
All Macs are configured about the same, HW & SW.

Can anyone offer any tips on how to troubleshoot this type of problem, before I give up and 'assume' that it is a HW (NIC) problem and toss the Mac in the Trash? (no warrantee left)
Our firewalls are not sync'ed to public DNS so we can't create rules by URL of playstore or appstore.

Our corporate mobile devices need to have push notifications & apps install :
what's the range of IP for appstore & playstore required & the ports to permit?

I heard appstore is a Class A subnet while playstore is probably a Class B:
is it a good practice to permit firewall rules to such big subnet ranges ?
We have a Mac server that everyone uses to access files that are stored on an external HDD connected to the server. What i need to do is take the Home shares people have and have them stored on the external hard drive as they are currently filling up the boot drive when in their normal place of MacintoshHD -> Users -> *
After logging on and while using his Mac OS X 10.9.5 computer a user repeatedly receives messages about things wanting to access and use the keychain similar to the message shown in the screenshot.

I have already performed first aid on the keychain and then verified the keychain but continue to get this message.

If we click the Cancel button this message continues to appear and keeps prompting for this password which we don't know.

What can be done to fix this issue?

I want to map FROM the windows 10 to the mac how can i do this ?

Hello I have a mac mini that was not purchase with our volume program and customer #, but when I log into the deployment program and try to enroll this one device to the MDM server I get this error ...Couldn't assign this device the data you provided my be incorrect please check your serial... any suggestions on incorporating this mac to this account?
I have 2 macOS 10.12.5 + HP 2055DN LaserJet + HP OfficeJet Pro 8210 all Ethernet [CAT-5] connected to Apple Airport Extreme.

Ever since I backed up one of the Macs with resident Acronis, a request to print from either Mac returns:

This printer has been paused. Do you want to resume printing?

If you do not want to resume the printing of jobs, you may add this job to the printer for later printing. If you select Resume and the printing of jobs cannot be resumed, this job will automatically be added to the printer.

Cancel / Add to Printer / Resume

The result of all this is NO Printing! Nada, Zilch - nothing. No matter which option I select or how long I wait. Rebooting all except Airport Extreme does not help. Sometimes the 8210 control panel displays ‘Printing’ - it does not.

As some of you may know, I have been trying for some weeks to establish a fixed IP address for this printer.l NO Luck Yet…

When I power up the printer, the IP address is: - before the Acronis backup, I could print from both Macs until the 8210 timed out and I had to reboot the 8210.

As you might expect I am getting desperate…

If it were not that I need the color printer and there is an AC unit in my office window, the 8210 would be a candidate for Defenestration.

A solution would be most welcome !!

Are there great benefits to keeping Bonjour programs on my computer.  I do not understand how it benefits me.  Is it network sharing?
Looking to help a friend who uses a mac - I only know windows.

He says it's running really slow.  Where would you start to troubleshoot?  

Is there an equivalent task manager to show what's running / what's taking processor power?

How do you tell if the hard drive is full? (is it the same as windows - you don't want the hard drive near full because of temp files /  etc?

How much RAM would you want on a machine these days? What mac would you say is just too old for casual business use these days?  Me, I don't like celerons or any other processors others than i5 or i7 (maybe i3).  Yes, core 2 duos run windows, but sevearl year old windows PCs just crawl with all the patches / updates / etc on a windows machine.  same for a mac?

And for windows, I'd want 8GB+ RAM.  4 would be the lowest I'd deal with.

Hi All I am trying to set up my DELL MFP Printer C1765nf to scan to my iMac.  They are on the same network, the printer is networked using ethernet and the iMac connects wirelessly.

I have created a scan folder called 'Dell' where it is shared and have created an account called 'printer' with a password and read and write permissions. 'Everybody' has read and write permissions.  I have gone to System Preferences and enabled file sharing and added the 'Dell' folder and the 'printer' user account.  I have also gone into Options and checked 'Share Files and Folders using SMB'.

Next on the web control panel I have entered:

Server type: SMB

Server Address: the IP of my iMac which I got from Terminal

Share Name: Dell

Server Path: Left blank as 'Dell' folder sits on my desktop

Server Port Number: 139

Login Name: printer

Password: <the password for printer>

Everytime I try to scan I get a Login Failed Error on 031-529.  Does anyone know what might be wrong?

All help appreciated!
Add HP 8210 Printer to Airport Extreme with USB

I have HP OfficeJet 8210 I want to connect to local Airport Extreme with USB and share with other Macs on same Airport Extreme network.

Currently I have to shutdown/restart the printer to get on the local network with IP address which is automatically assigned at printer restart.

How do I assign permanent IP address ( to printer so that printer restart not needed and printer will be available to all local network users?

On setting up a mac server its host name is server.local would this have an affect on deploying profiles remotely to it? Thanks

I have an old mid-2009 MacBook Pro which I am currently using to try to access my newly-installed 1Gbps internet connection. Looks like I can't do that, because 100Mbps is the maximum my machine can do, according to several speed tests.

So I'm thinking of connecting an external USB wireless adapter to get as much speed as I can for my Wi-Fi. What make and model is best for this problem? I'm running El Capitan (OSX 10.11.6).

Thanks for all suggestions!
I've recently installed a pair of iMacs running MAC OS Sierra on a network with a Windows 7 64bit Pro PC acting as a fileserver. I added the various shared folders as favourites on the Finder sidebar however once in a while the favourites vanish and need to be re-added.

At first I thought it was perhaps because the iMacs were connected to the network via WiFi and the connection wasn't established before the computer tried to somehow validate the favourites so I've wired the computers in but it's made no difference.
Is below a real Apple.com site asking a legitimate login request (my account will be locked for a week, then deleted) or a scam. Page looked legit. I was able to login to Apple.com OK - should I continue with this request? e.g. who is 'www.votsalo-construction.gr'

I have a TWC modem (no hot spot available), airport extreme router, and server. I have two PC with Vista that are connected. I am trying to connect my tablets with Window 7. These tablets were in use before the upgrades of modem, airport, and server. Now, the tablets will not reconnect to the airport/internet. I have performed all window 7 updates. The connections icon shows the network's name but does not allow connection. Also, the connection icon has a yellow star to begin with.  I have unplugged- and-plugged the modem and airport too.  My public network is connect on these tablets.
Anyone know of a good site for online training. I am trying to get the Apple 10.12 certification. Also I am in Indianapolis and it looks like there are no testing centers here. The closest testing center is in Chicago. Is this true? Any advice on Apple Certs would be greatly appreciated.
half our computers are now macs. Should we update our Windows server?
