PArdon the dumb question.  Not really an Apple Person. I have to install an IMAC w/ an Airport Time Capsule at a client's location tomorrow. They have an existing wireless network but, I'm not sure if it is Apple or not. How do you configure the Airport to use the existing wireless network?  Of note. the location is very large and the Time Capsule won't be near the Modem or router.

What are the shortcut keys or method that can be used on Mac OS X  High Sierra v. 10.13.3 computer to switch from displaying the standard Mac login screen (which displays the usernames & their icons as a list of users to logging on using a User Name and password (so a user can login with an Active Directory account)?

This is something that needs to be done before logging onto the Mac.

The option to display the login windows as: Name and password (instead of list of users) has already been selected (see the screenshot).

For whatever reason when this computer powers up it displays the logins as the list of users. These users are local administrator accounts that only IT should have access to; we don't want the users using or accessing local accounts. The users should only login using their Active Directory usernames and passwords.

So what are the shortcut keys or method that can be used on Mac OS X  High Sierra v. 10.13.3 computer to switch from displaying the standard Mac login screen (which displays the usernames & their icons as a list of users to logging on using a User Name and password (so a user can login with an Active Directory account)?

Let me know if any further information is needed.

setting up AirPort Time Capsule to only work as backup disk (and not as wifi router)

I want to use my Apple Time Capsule just as a network attached backup drive and not a router.

This what I have done:

(I got the following instructions off of

To prevent the Time Capsule from acting as a WiFi access point or router, and use it only as a backup disk, just open the AirPort Utility app on a Mac (Applications -> Utilities -> AirPort Utility) and do the following:

1. Select your Time Capsule and hit Edit.
2. Go to the tab labeled Wireless
3. From the Network Mode pop-up menu, choose Off.
4. Click Update, and the base station will restart and load the new settings.

OK. So I did all that. The AirPort Time Capsule restarted. But now the computer cannot find it when I go in to the AirPort Utility.

See screenshot:
Oh boy. So now what did I do?

I think that the instructions that I got from that website lead me on the wrong path.
A company I am working at has Mac laptops that all have local user logon accounts.

We have added a Server 2016 domain controller and the users will now be signing onto Active Directory to log in to their Macs.

What utilities or methods are available to migrate all current settings and data from these user's local Mac logon accounts into their new Server 2016 domain logon profiles on these Macs?
Currently experiencing an issue with access to mapped drives using SMB protocol with a MacBook Pro running High Sierra, we only see this issue with that machine. The problem effects the user when attempting to move or rename a file in on the share, the MacBook becomes hung up, showing only the spinning pin wheel and needs to be completely restarted in order to allow the user to use the computer. I found the article below attempted recommended changes (no resolution) also opened a ticket with apple support and was directed to open a pay per incident ticket because the technician had no insight other then what I performed on the issue other thanking for directing him to apples article and saying that what he recommends I should attempt.

Does Apple have any utilities that enable the browsing of Mac OS X backups to view which folders and files are backed up  and to do things such as perform manual restores of Apple OS backups to original or alternate locations which a Mac admin can perform from a centralized location rather than having to do this from each individual Mac user's machine?

My organization has several Mac OS X laptops which are all backed up using Time Machine to a Network Attached Storage device (NAS).

We are interested in any centralized management solutions for administering the Time Machine backups if possible.
Here are two Macs running macOS 10.13 in a WLAN, sharing a freshly installed QNAP NAS box for SMB file storage and Time Machine. While Mac A is behaving perfectly normal, Mac B can't see any of the services on the NAS: neither the SMB shares nor the Time Machine show up. Pinging the QNAP works, though.
Plug in an Ethernet cable in Mac B and all is fine, just like Mac A.

I've checked just about anything about the WLAN I can think of: firewall and misc. TCP/IP settings, DHCP, duplicate addresses, ARP and DNS caches, VLANs, 802.1X etc. - to no avail. Why in the world can Mac B ping the QNAP box but not see any of its services? Why is only WLAN impaired, why does the cable work?

Quite bizarre. Any suggestions what else I could check? I'm just one step from re-installing macOS ...
I work in a hospital. We use the Stratus iPad app for interpretation.  We have a guest internet circuit that these iPads are on.  The circuit was recently upgraded from 35 Mbps to 100 Mbps. No other changes that i know of. Around that time the Stratus app stopped connecting. There is an asa 5505 on this circuit, but only default config is enabled.

 I took the ipad home and the app worked fine on my home wifi.  I ahve contacted the vendor and our ISP. Both claim it must be a firewall issue, but nothing has changed.  Any ideas?

I had created metadata tags for all of my photos before I had them imported into photos for the Mac. I would like to auto create albums based on the tags in the photos.

I know I can do this with SmartAlbums, but those don’t transfer to mobile or other Macs so I need real albums.

I was thinking with AppleScript I could do something but not proficient there.  Maybe created the Smart Albums from the tags then create albums from all the smart albums?

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.

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
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 …
Good morning, Everyone!

Yesterday Apple released a security update for Mac that you should download and install immediately. To be brief, it closes a hole that allows a user to bypass Administrator authentication without using the Administrator password. The download isn't very big, so it won't take too much time out of your day to update your system.

Have a great day EE fans and Experts!

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 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)

Thanks for the head's up Andy! I already did the update last night and fortunately for me, I'm not using Microsoft based email so the issue didn't bite me. Big bummer for those that were hit with it!

And yes, I'm loving this update! The new dock on iPad is the real standout for me, along with the multi-tasking improvements. iPad is feeling like waaaay more of a desktop replacement in a lot of cases now. (Although the downside is how it's starting to make me crave a bigger screen, like the larger iPad Pro model. All part of Apple's nefarious plan to sell more iPads, I'm sure ;-)

On iPhone, the new Control Center is pretty sweet.

Still exploring a lot of the changes though, but this feels like one of the best major iOS versions in a while (well, other than that Outlook bug. That part is lame.)

We drew straws in the office today, who should be the gambler and upgrade, last time we upgrade a major iOS we ended up with a brick!

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 ?

hi techs,
I am trying to play videos and pictures from my Note 5 to my Apple TV and suddenly it's not working in the last one year or so. The last time at work successfully was about a year ago and I was using allcast.  this week I've been trying to connect my phone again and no matter what I try my Note 5 will not detect the Apple TV and if some of the apps do list it it will not connect. I also tried my work Android phone which is I think an S7 and it wouldn't connect either. I have reset the network connections several times on both units and tried repeatedly with no success. I'm starting to wonder if Apple has made a change that everybody but me knows about. at this point what I think I'm going to do is buy the Chromecast and plug that in right alongside the Apple TV to see if I can use that to interface with my phone since all of the apps I've downloaded aren't working at all. My Note 5 is up-to-date with the most recent software and the Apple TV is also up-to-date with the most recent software and it is only about one year old. Any assistance with this issue is appreciated.
 thank you

For those of us, that like seeing our alma maters take a pigskin and strategically move down the field, you'll be happy to know that ESPN on the 4th Gen Apple TV has just made it an even better experience. You can now watch four games at once! That means you can watch your school's arch rival, the arch rival of your spouse's school, your alma mater, and your husband's/wife's alma mater all at the same time. Since my wife is an ND grad and I'm a Cardinal, we can now both poke fun at each other while being in the same room (no more separate TVs), which ultimately means the buffalo wings and Guinness are in the same room too. If this is not reason enough for you to get excited, then how about the other great things that come with the autumn season: the grass is barely growing, holiday cheer is in the air, and pumpkin spice is back in your coffee mug. Either way, I hope the autumn season brings you the happiness you deserve and that your school makes it to a bowl game.

This sounds pretty cool! I'm especially excited for Disney's recent announcement that they will have a dedicated ESPN streaming service that isn't tied to a cable subscription.  I just "cut the cord" again, and live sports are really the only thing  that we miss and is frustrating to access.

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?
