Install macOS that Sierra is trying to add a new support tool

When you try to install macOS Sierra I get a popup asking for my password that says "install macOS that Sierra is trying to add a new support tool". I have never had this with the previous updates and research of these discussions and more generally on Google pulls a vacuum. Is it safe to put my admin password in and proceed with the installation?

I can tell that you have no option to move forward.

Is it safe? We can only assume, if you trust the big Apple.

  • I can't Thunderbird to recognize the password for the gmail account, that I am trying to add.

    I am trying to add a gmail account to Thunderbird that already hosts several gmail accounts. No matter what I do, I can't recognize the password in Thunderbird. I admit, I was wrong a few times, but I got the right one, and it was typed in perfectly several times, as well as copy and paste. The password worked well to log on to the account directly, but not in Thunderbird. I tried to change the password, and that doesn't work anymore. I tried to add this account in Windows and Ubuntu 14.04 8.1, and the results were the same. In Ubuntu, I tried adding add another account that I needed, and which took place without a hitch. The only thing I can think is the address that I am trying to add is linked to an email address for a Web site being transferred to me which is hosted by Yahoo and his business correspondence. I tried to add the account yahoo directly, but I add the same problems with passwords, but I suspect that most of you know that it's because Yahoo is simply suck more to try to become irrelevant.

    I can't believe how quickly you help on this forum, a few seconds, you guys solved the problem and the account has been added with any other questions. People on this forum rock!

    Now I'm beginning to suspect that he indeed had to do with this first batch of bad passwords.

  • 50 Firefox wants to install a "new support tool", what is it?

    I downloaded Firefox 50 via the built in update. When I type restart to install the update, I get a window saying that Firefox wants to install a "new tool of assistance" and that I need to enter an admin password to complete the update. I can't find anything on this "support tool" in the notes version or via a google search. I was just wondering what is it? 10.11.16 running OSX. Thank you.

  • Java 8 71 update tries to install a new support tool?

    I received a window indicating I should install a new version of Java. During the installation, a window came "update Java 8 71 trying to install a new tool of assistance." I went on the Oracle web site to learn more, and he says: "Oracle has partnered with companies that offer different products. The Setup program can offer you the option to install these programs when you install Java. Specify whether you want these programs installed, and then click Next. " At this time, I canceled the installation, since I started to worry that allowing the"Helper"install could infect my system. Thus according to 'I'm still 66 update on Java (System Preferences/Java). My question is, someone knows it more on the 'Helper', and should I allow to install? Thank you.

    BTW, I went to get the .dmg file in the case where I have to re - install and can't find it. I expect it to be in the downloads folder but not so much. Where should I look for it? Thank you!

    Yes, you can allow it. However, if you do not use Java or applications that need it, then you need not to install Java.

  • I am trying to add a new design for a site!

    Help, please! So I'm still trying to understand exactly how dreamweaver works, but I know my way around the block at least.

    I created a site in dreamweaver and I have added to my godaddy FTP server and successfully launched and it worked perfectly!

    Long story short: I'm just recently re-designed the design of the site with new images and a new index.png from a model that I used. I'm trying to repalce design that I had with the new design here. I'm not sure what I'm doing wrong! It will not work, I tried everything!

    Please tell me what I am doing wrong:

    I created a new site and a new name and new root folder also pointed out with my new design. I deleted the old site and I even deleted the root files on my computer even the index.html file and I've connected my new site on the server remote and "put" everything there and it is leaving my site with the old design. There are more NO TRACE of this drawing on my computer.

    ALL I want is to update this site for the new design and to get rid of old, outdated one I had before. Help!

    There is always a file (with the old design) root named "index.html" in the folder on the remote server.

    This file will always be displayed when you point your browser to the site

    In other words http://www.ovtliers.com = http://www.ovtliers.com/index.html

    The new design is at http://www.ovtliers.com/index3.html

    1. Visit the remote site for index.html (old design) in the root folder and delete it.
    2. Rename "index3.html" (in DW) to 'index.html' (click Yes to update the links), upload all changed files and then test again.

    What to say?
    IE in the SGD server db already has the same PB? but I have never added, it's possible have same db

    can someone tell me?
    Thank you very much!

    Hello

    This shows the target PROD already exists in the repository.

    Remove it from the repo as well.

    SQL > exec mgmt_admin.delete_target ('targetname', 'targettype');

    Example:

    SQL > exec mgmt_admin.delete_target ('PROD', 'oracle_database');

    Once it is erased re add again the target. And it goes great with any questions.

    Best regards

  • I deleted my email account and tried to add it back, but it is said that there are already. It drives me crazy...

    I deleted my email account and tried to add it back, but it is said that there are already.

    First of all, make sure that you don't have two accounts with the same address. What happens if one of them is an iCloud account.

    From the Mail menu bar, you select

    ▹ Connection Doctor window

    In the window that opens, look for an SMTP (outgoing mail) account with a name that corresponds to the account that you are trying to add. Double-click it. Another window opens, displaying the list of all outgoing mail accounts. Click the sign button less to remove the corresponding one, and then click OK.

    Try to add the email account again. If you still can not, log off or restart the computer, and then open the preferences window accounts Internet and check if the account is displayed.

  • I can't add a new contact on iPhone 6s

    Recently got a new iPhone 6 s. I tried to add a new contact and phone number to my existing list.

    There seems to be no problem until I checked the list and the new contact was not there.

    I looked online and saw another way to do it, by dialing the phone by clicking on the sign more number.

    It was supposed to take me to the page contacts where name etc can be added.

    I did, but to enter the last digit, the sign disappeared. So I tried again but this time

    I thought I would omit the last digit and change it after. Well, it's the same thing.

    Everything seemed fine, but... There is still no sign of him on the list of contacts.

    Even the contacts search shows nothing. Any advice?

    Especially this declaration, supported by the rest of your post, suggests that there is more than one source of your contacts.

    When I think to education "[I] recently received a new 6 iPhone" and I think to enter contacts into an iPhone brand new (without any other reference in your post), I think that you manually type them in.  They would be stored locally only your iPhone, or maybe in iCloud if you have turned on iCloud contacts.  In one of these two scenarios, entering the future contacts would not be a problem, because they would be placed in the only and unique casing that you put in place.

    But in your case, since you never mentioned where your contacts are housed and had this phenomenon of missing contact, it is very likely that you are housing your contacts in several places (e.g., Facebook contacts importers?).

  • Don't have the original keys, how can I add a new version?

    Hello everyone. Some time ago I posted about an error message I was getting when I tried to add a new version of an existing application. The error was:

    File bundle (MyApp.bar) was rejected. Package ID is required for all .bar file. If this is an upgrade, ID of Package must match ID of Package in the bundle of original file.

    My Package ID are correct, and after contacting the support AW repeatedly told me to sign with my original keys. Problem is I don't have my original keys. Is there any way I can update my app now?

    Sad thing is - no.  The "signature" application is the app id + keys which makes the unique application on the device.  Without the original key, the software will not have same signature.  He was advised by RIM to save files of related keys (necessary database search form).

    One might think that RIM would maintain a copy of which was distributed to a developer to be able to re - download and avoid this mess.  Or the opportunity to re-edit the keys short of context.

    Here there was better news.

  • I used to be able to add new files in libraries by clicking on the tab 'add a new folder '. Now it does not work.

    When I go to the library to add a new folder, it does not work.  I used this method, many, many times with no problems.  I have not tried to add a new folder in about a month, I think.  I clicked on the file I want to add a subfolder to do a right click.  He asked new portfolio name.  I find that odd because I have this experience only on my desktop and my laptop.

  • Problem with 'Add a new value' component functionality

    Hi all

    I'm having a problem with the component feature 'add a new value '.  The component is designed to add an instructor for the purposes of accreditation.  When a new teacher is added using the component, it is added to a table for certification.  The search folder search this table allowing the user to update an existing record of instructor. Add the search folder for the component is a view of PS_PERSONAL_VW, which excludes the entries in the table of accreditation.  The only key to scroll 0 is emplid accreditation file. When an attempt is made to add a new employee, I get the error - "the value that you have tried to add already exists. Please specify a new value in the above fields. ", despite the fact that the selected employee was not added and is not in the table of accreditation.

    Someone has an idea of what the problem is here?
