Why do I need to have and use a keychain if I am the only person to every use my Mac?

Is netflix the best for movies?

Netflix is a great service to use, and works well on AppleTV, any IOS device and your computers. Netflix is great for TV shows by season, and usually get the latest movies 30 days of their release.
Keychain is also there for security against applications accessing passwords, not just users.
The keychain service found on Mac OS X is significant for two major reasons. First, it uses strong cryptography. Over time, many applications have provided the capability to store passwords but have failed to do so in a way that can be trusted or considered safe from compromise. Second, the storage and retrieval of all passwords is handled by a single service, not individual applications. After you have decided to trust this service, any time you are asked to store a password you don’t have to worry about the means by which it is protected. What you do need to be careful of, though, is what applications you allow to make use of your keychain(s). When you unlock a keychain and allow an application to access a password, you open the door for that application to slip up and compromise the security of that password (more on this later). Although the keychain provides strong secure storage for passwords, any application can make use of the keychain API. Thus, be mindful of the applications for which you grant access to your keychain(s)

  • Do I need a user account if I am the only person using my Mac?

    Hi. Total newb to Mac here so be gentle with me What I am wondering is did I need to create a user account for myself when I am the only person that ever uses my Mac? The reason I did create one is I did not see an obvious way to create a password upon boot up as a straight admin account & I am concerned about theft. So I guess I am asking a few questions. Do I need the standard account & if not how do I delete it?
    If I do not need one can I set up a login PW for OSX period?
    I sincerly thank any help.

    See: http://support.apple.com/kb/HT3309
    Go to ->System Preferences->User Accounts.
    As the only user, you must have at least 1 User Account for yourself (as Administrator)
    To delete an account, hightlight it and select [ - ]
    For Password on Boot, select Login Options and set Automatic Login to OFF
    Note that if your Mac is stolen, its very easy to bypass the Password on Boot.
    For Security, see  ->System Preferences->Security->Filevault 
    Personally, I think Filevault is overkill, so I just put my sensitive date in Encrypted Disk Images: http://www.macworld.com/article/53658/2006/10/decmobilemac.html

  • What are smart mailboxes and why do i need both smart and "normal" ones?

    What are smart mailboxes and why do I need both smart and "normal" mailboxes?

    Hi Kingoftypos,
    Thanks for that clarification. So, now it appears that the ultimate purpose of a Smart Mailbox is to point to all emails that meet the criteria in a single place, so if they are spread among several mailboxes, you will be able to see them all together. Here is an article from Apple that describes it:
    A Smart Mailbox displays in one location messages that are stored in other mailboxes, so you don’t have to move messages between mailboxes. The messages displayed by a Smart Mailbox are based on criteria you define, and are automatically updated to include new messages that match your criteria. For example, you might create a Smart Mailbox that displays all messages found in all mailboxes from a specific sender.
    If you change a message in a Smart Mailbox, such as marking the message as read or unread, or moving or deleting the message, the change is reflected in the mailbox where the message is actually stored.
    So, adam, I would think that, if you had mail going to a lot of different places, and wanted to be able to see a particular set of those in a single place, you would use a smart mailbox. Maybe use the rules to direct your mail to different places to start with, but a smart mailbox to bring a set of common ones all together into a single smart mailbox?
    Maybe you have Rules move your Amazon mail to an Amazon folder and your Apple mail to an Apple folder, but then you have a Smart Mailbox that contains any mail that has the word "Receipt" in the Subject line?
    Just a thought....
    Cheers,

  • Why we dont need sender agreement and comm channel in IDOC to file scenario

    Hi,
    there are 2 queries:
    first query :
    Scenario is "Idoc to file transfer"
    why we dont need sender agreement and communication channel for IDOC to file ,while we do need
    both of these for "File to RFC "
    Answer : which i got is because IDOC sits at ABAP stack but same is valid for RFC also.
    Then why For "IDOC to file" we dont need that.
    Second query:
    Also when i did scenario for File1-RFC-File2 scenario using BPM i have created a interface
    between XI-RFC synchronous to send data which we got from file1 in XI to RFC importing parameter
    and getting data from RFC back to File2.
    Here in IDOC to file scenario why we dont need any interfface for IDOC-XI Asynchronous.
    Regards,
    Mayank

    Dear All,
    For file to idoc scenario is there any possibility to get line items details or xml details i.e the segments and its related field details using reference id, transaction id or interface name or message id in SAP PI 7.0. I know we need to click each and every message in sxi_monitor and look for details.
    For SAP(R3 System) I can create a report and set the job for specific time period so automatically it throws the details(like reference no, document date, invoice no from) in ftp path as .csv file. The same ftp path is maintained in program.
    I wanted to check FTP--->PI postings and I have set the job at r3 system it is working fine and Im monitoring it too.
    Now the end to end scenario is FTP--->PI--->ECC(R3 system). Please help.Many Thanks.

  • Why do we need to have a observer run on the different computer

    Hello team,
    Why do we need to have a observer run on the different computer and how to install & confgure it on that different computer.?pls help
    5.5.6 Managing the Observer
    The observer is integrated in the DGMGRL client-side component and runs on a different computer from the primary or standby databases and from the computer where you manage the broker configuration. The observer continuously monitors the fast-start failover environment to ensure the primary database is available (described in Section 5.5.2.1). The observer's main purpose is to enhance high availability and lights out computing by reducing the human intervention required by the manual failover process that can add minutes or hours to downtime.
    Thanks

    Thanks Aman,
    Do we need a same db binary & OS version for starting the observer on the different computer ?? here the primary & standby are liunx.
    Thanks in advance..
    Regards,it does not have to be on the same platform or operating system on which the databases reside, and it does not need Oracle EE and an instance (which means no extra license).
    To configure check this.

    Why do i need to download and install a huge piece of software just to purchase a gift for someone?  It seems like very bad business practice to me!

    Stores only have gift cards, and because I live in a different country to the person I want to send one to, that isn't practical.  Installing itunes, seems excessive, especially as I would first have to install wine on linux, just to buy a gift for someone.

    My IPad 2, IPhone 3GS ans iPod  no longer work with apple TV, I have 2 apple TV in my house and for he last 3 weeks the iPod was the only one we could use for appleTV now none of them works, the apple TV icon does not show up any more. Re-started everything.

    Ok thank you so much, for your timely response.
    RESPONSES:
    1)   When I set up my iMac, I did not transfer any data directly from my windows PC.  I simply used the same iTunes login and account.  I have access to all of the files via the "Purchased" section of the iTunes store.  If I click "Download Previous Purchases"  text, I can download ALL of the purchases I have ever made.
    2)   I have the Apple TV 2, so good news, question answered.  I thought maybe it was the Apple TV 1, but it is the Black model, so bam.  Good response for you.  Well the whole damned reply is an awesome response, just pointing out that one piece of awesome.  I stated that it was an Apple TV 2, and yet you were still good enough to figure I could be mistaken, and provide me with knowleedge just incase.
    QUESTIONS:
    3)   So can my iMac not stream the data directly from itunes, without download?  Apple TV can, but perhaps that is something among many things that maker it unique, and awesome.
    SERIOUSLY.... THANK YOU... 
    I work in the computer support section for the Military.  The only problem is we use Windows , lol.  Well that and i've been gone for nearly 6 months on recover.  I go back next month though I hope.  But working in that field gives me the abilty to judge responses that run inside the same vein.  Your response was so awesome that I half thought I might have written it myself.

    You won't really be deactivating any extract structure or datasource because it will stop data transfer. However if you change the structure and do not activate it then it will be in modified version (or deactivate state) for system.
