Since I'm not familiar with the MAC, (in fact, I don't have access to one) I have not encountered this syntax before.

In a set of Release Notes, I need to document a feature involving the MAC key combination COMMAND and Click.  Two questions:

1. What's the preferred syntax here?

Something else?

2. What's the correct verb? Press? Perform? Do? e.g.
Press <Command>-<Click>

I have a Sarbent Hard Drive Docking Station (DS-UBLK) and it was working perfectly fine. A few days after I updated OSX (10.13.3), I no longer see the icon. I can't find it anywhere.

I talked to the support at Sarbent and they just sent me another docking station which doesn't work either.
They have a driver for windows, nothing for mac.

I borrowed another docking station (Thermaltake BlacX): nothing.

Could there be a problem with the new OSX update? Or maybe that's not the problem at all. Could my harddrive just be dead?

I found a similar question here:'t-my-laptop-recognize-the-Thermaltake-Blacx-hard-drive-docking-station.html

But I'm not computer literate enough to know if I have the same problem.

Also, I tried to downgrade the OS to before the update. And you need Time Machine for that.
The problem is that the hard drive I use for my docking station IS the Time Machine.

Thank you.
Soft reset of airport time capsule returns ‘password not valid’

After entering soft reset mode for Apple Time Machine, attempt to clear (delete) password, with Airport Utility, (i.e. reset/update time capsule guest account) failed and returned ‘password not valid’

My goal was to have no password requirement for guest account - users could connect to LAN with Windows 7 laptop without name/password requirements.

How do I achieve this setup?
I need an OS agnostic script or HTML page created that will spawn VLC player and open a static UDP stream.  I already have an HTML (actually a .hta) file that will work on Windows machines using IE.  However, Chrome and Safari won't allow me to open VLC links on OSX, which is my next OS to deploy this to.

We have school buildings with internal live stream "channels" provided by a Marshal VS-11 appliance.

I'm attaching a slightly redacted version of my current hta file, I might have had some editing mistakes as I tried to remove school names.  I'm also attaching screenshots of the UI.  Also is a basic diagram showing my hardware setup, for reference.
I got a computer and need to know how to reset it. I got it at an estate sell, the administrator is locked in and i dont know password. Cant use internet
A customer brought in a macbook pro laptop and when she attempts to go to her online bank account she gets an error message, "Safari can't open the page "" because Safari can't establish a secure connection to the server ""

   she can open any other web page she wants and I went on my computer and went right to the website no problem.  

I reset safari (all boxes checkmarked) but that did no good.

What do I need to do to make it work?
can macbooks/apple macs be joined to a windows AD domain and used by end users in the same way as a domain joined windows 10 laptop?

Or would there typically be an additional application on the macbook installed to allow connectivity to the domain, e.g. file servers and applications, and the devices not directly added to a companies AD? I'm a tad confused how these devices would be managed, as I don't suspect you can deploy group policies to macs for example to lock down USB ports etc, as you can with windows devices.
What are the best software programs for performing file comparisons between 2 different folder locations within a Mac OS X computer?

I need to find out which files and folders exist in one location that don't exist in the other location and if there are any differences between the files within the two folder locations.
Hi All,

I have a question regarding MAC. We have about 75 MACs in our environment. We would like for users to have an shortcut on their desktop that will lead them to our Intranet or set the default webpage to in safari to our Intranet.
We are using Casper server (Jamf pro) V. 9.10
Is it possible to push it out using configuration profiles or managed preferences.

Thanks in advance

I am on macOS High Sierra. Office 365. Trying to mail merge addresses on to envelopes. Used an Excel sheet with the addresses and using Word to merge. All is perfect EXCEPT: the envelopes print on both sides. It's an Officejet Pro 8600. Never have this problem, and I can't find an option (after being in mail merge) to say, "No, stupid, just print on one side."

I am using Parallels Desktop 13 for Mac Pro Edition(Version 13.3.0(43321)), and  I am trying to upgrade Windows 8.1 VM to Windows 10.   I keep getting the following error: 0xC1900101-0x40017 The installation failed in the SECOND_BOOT phase with an error during BOOT operation.  Note that before trying to upgrade, I ran Windows Update and installed all important updates and my Windows Firewall is turned off.  

Any suggestions?
I would like for my mac users to be able to change the passwords for their Active Directory Accounts from their Macs.  These users do not have domain joined macs and connect to my network to get web access and email access via Office 365.   Their password policy recently changed from "Never Expire" to require a password change.  These users need to be able to change their domain passwords either by a command or by some type of software.   Macs are running OS 10.12.6 Sierra.   I don't want to to join Macs to domain, I just want them to be able to change their domain passwords from their Macs.  Also, they will not be able to change thier passwords using any web portals.
Just recently replaced a failing Server 2003 server with a Buffalo NAS unit running Server 2012 Storage Server R2 - this is a small shop so this unit is working nicely so far with the following exception.

Transferred files off the Server 2003 box onto a NAS share and all operations are functioning properly for all users.....EXCEPT 2 MAC users who access files off a share setup for these MAC users to work with. When these users browse the Window share using "Finder" - they do the initial connect fine. The drive is mounted and an alias is setup on their desktop. All the files will display in the share for a few seconds..and then the file share window will do a refresh...and all the files disappear. The files are still on the share..they just disappear from the MAC view. It's the oddest issue. No problem for any of the Window users...just happening to these 2 MAC users.

My last effort today was to add the username/password these MAC users use when they log onto their MAC systems (they don't have to put in the password..the MAC's boot straight to a desktop after a restart/power-up) - I added these same username/password to the "Local Users and Groups" on the Server 2012 - re-propagated permissions on the share...still no go.

Looking for a life-line as I'm out of
Here's the use case:

iOS 11 on iPhone form factor
Mobile Safari
WebRTC (web not native, they are different somehow)


- WebRTC video is blank and no audio
- Does not ask for permission to use the camera or audio
- Used to work in an early iOS 11 developer beta
- Same code works on iOS tablets and MacOS desktop Safari

Seems to be broken in iOS on a phone form factor only (iPhone/iPod Touch).


What could be different?

I need to be able to clear the Recent Documents on my Macbook which currently shows the last 1500+ items I've opened.
The APPLE Logo, Recent Items, Clear Menu doesn't clear the items in Recents when I open Finder.

Anyone got a quick and easy way to do it via Terminal?

By the way, to clear all the up arrow / down arrow history in terminal type history -c and press ENTER.

Hi, I have an internal Adobe Acrobat from that I have made to be filled out, and also use it for calculations.  All my PC user can use it fine, my Mac users can not.  The field that is supposed to calculate miles and also calculate dollar amounts, does not work.  The fields stay blank where the calculations are.  I have text fields that populate on another page, and that works.  I have downloaded Acrobat Reader for Mac, downloaded the form to their desktop, and then opened from Acrobat Reader.  Are they any solutions to this?  Do I have to create the form on a pro version of Acrobat for Mac? I'm getting ready to redo the whole form on a Mac, but the form is complicated, so checking here first before starting it.  Thanks for any help!  
I have an original video that is 1092x820. I'd like to make this radio 16:9, so something like 1280x720.

Could I create this as a "letterbox" video in Final Cut Pro, meaning can I create the 1280x720 project, import the 1092x820 video and get it to fit inside of those constraints?

Any suggestions on how to do this? (I'm a newbie at FCP X).

A Mac OS X user was running an older version of Google Drive on her Mac to connect to a corporate Google Drive structure where our organization stores files within the Google cloud.

A week ago she received a prompt to upgrade to Google File Stream and proceeded to perform the upgrade.

She then uninstalled Google Drive.

Now her computer has been having persistent issues updating existing files and downloading new files.

When we open Google File Stream it always says that it is running and syncing. Also her computer constantly maintains a connection to the internet.

She is able to fix the issue by rebooting her Mac and then it will sync the latest changes and download the newest files. However, she has to reboot her computer several times a day.

What can be done to fix this issue?
The attached  javascript code works on W3Schools using a  Windows browser  but not on Mac Chrome or Safari browser. I started by using the Try it example for the slice operator. I inserted some code from a routine that returns CST from (Central Standard Time). It works when I do the exercise inside w3schools on a Windows browser. When I repeat the same process using w3schools on a Mac Chrome browser it doesn't. It complains when encountering the slice operator.

hi Mac folks

as you might have known that, for some reasons, macOS HS has removed Translation Widget from its Dashboard, and one of the workaround methods is to copy the widget from previous OSX or macOS to the HS installation's /Library/Widgets folder.

I did that, copied the Translation.wdgt from my Mac Pro running El Capitan to MacBook Air running High Sierra.

But, it doesn't work as expected: as shown in the screenshot below, the copied widget can be added into the Dashboard, but it doesn't work at all because the language fields can't be switched or selected.  the fields just show <b>nothing</b>.

do you have any idea what to do now? thanks.

kind regards.
