  • Mac Mini - DVI to ADC Adapter - Cinema HD 23" ADC anybody?

    I would like to buy a Mac Mini, but I'm not sure if it will handle an old Cinema HD 23" ADC through a DVI to ADC adapter. Anybody has this configuration? Which is the maximum resolution possible?

    Hi
    unfortunately I think the Apple store have sold you the wrong item.
    I'm almost certain the DVI to ADC adapter only works with ADC based flat panel displays. DVI ports can output digital or analogue signals (or a combination of the two). The adapter seems to provide digital, which is why it works with the LCD displays, but not analogue, which is why it doesn't work with the CRT displays.
    Confusingly Apple did a 17" Studio display both as a CRT and LCD.
    Dr. Bott do a similar adapter but they explicitly state it's not compatible with the 17" CRT.
    Unfortunately I'm not sure there's a solution, as the display has an ADC connector yet I'm not aware of any adapters available that will work.

  • I want to use 2 screens on a mac mini, which cable di have to buy extra

    I want to buy the mac mini but i am not sure what extra cable to use to work with 2 screens from Dell.(DVI).

    You need to purchase an min-display port to DVI adopter.
    The Mini comes with an HDMI to DVI adopter.

  • Mac mini (Late 2012): Dual- or Quad-Core?

    I'm upgrading from a MacBook (2006) and - as a frequent iPad user - am thinking of just getting a Mac mini. I'm not sure though as wether to get the i5 dual-core or i7 quad-core version.
    What I'll be using it for (none of these on a professional level, prosumer at most ;)):
    Photo editing (iPhoto, thinking of switching to Aperture)
    Web development (Coda, Espresso, local test server)
    Designing (Sketch 2)
    Full-HD video editing
    Web, office, social media, ...
    Can I expect a signifcant performance boost at these tasks from the quad-core model or will the differences be barely noticable (also considering most of these applications will be running simultaneously)?
    I'll be maxing out RAM from a third party vendor in both cases, HDD capacity is not important and I'm not going to upgrade to SSD or Fusion Drive.
    What do you think? Any thoughts appreciated!

    Thanks for your insights! My inital goal was being cost-efficient; Fusion Drive is only an option on the quad-core model thus making it 1080 Euros were I live. That's almost an entire new Mac mini which I could buy in 2-3 years. I don't mind CPU intensive tasks taking longer (e.g. rendering final movie) as long as the actual "creative process" runs smoothly (e.g. cutting the movie).
    As you both said finding out how/if apps take advantage of multiple cores is not that easy. I guess I'll have a closer look at all the benchmark tests and reviews that will be showing up in the coming weeks.
    I think Fusion Drive on a dual-core might boost performance more than just going quad-core, unfortunately this is not an option for the lower end model. Also I want to wait a little to see if Fusion Drive is proprietary Apple hardware or just implemented software-wise (which would mean I could fix a broken drive myself after warranty has expired).
    By the way, any guesses on Black Friday sale options (as far as I could find out the Mac mini wasn't included last year)?

  • In order to properly play my music on my DAC with a headless mac mini, I had to "check" the tunes in iTunes. When I did that, the songs in each album were put in not their proper order. How do I restore them to their original sequence in each album?

    In order to properly play my music on my DAC using a headless Mac Mini, I had to make sure that all of the songs in "Music" were checked. To so so, I pressed the "check box." When I did that, all of the songs in each album were resequenced in not their proper order.
    How do I restore the proper order of songs for each album?

    In list view, select the album column. To choose which columns appear, select an item on the left side of the window (a playlist, for example), choose View > View Options, and select the information you want to see. You can also Control-click a column heading to select columns to display.
    The column selected determines how tracks are displayed.  For example, clicking the "Name" column displays all tracks in alphabetical order; clicking the "Album" column displays the tracks in album order; clicking the "Date Added" column displays the tracks in the order that they were imported into your library.  Columns also have a disclosure arrow at the right of the column (when selected) that you can click to reverse the order.

  • Is there a way to upgrade my mac mini's video memory?

    I want to have a new video/graphics card for my mac mini, but i'm not sure if it's possible, and if it is possible how to do it.
    Please help!!

    16Gb is the maximum amount of memory the MacMini will support. I have a Mid 2011 MacMini server that I have swapped the 2 500GB spinning hard drives and Replaced them with a 1.5TB spinning Hard Drive & a 240GB SSD (ssd being my boot drive) the SSD with mac a night a day difference in the day to day operation of your mac mini.
    Here is some of what I have done to my Mini:

  • What type of monitors can I use with the Mac Mini?

    Hello,
    I was thinking on purchasing a Mac Mini. I was not sure if the monitor I have at work with function with the Mac Mini. It is a: 20" ViewSonic Professional Series P815...
    Does anyone know if this monitor will work with any Mac Mini? Is there an adapter for it?
    Thanks.

    It would be fine for them all - all minis have come with DVI video connectors and adapters to convert that to VGA, so aside from the possibility that the Viewsonic might suffer the greyish or dull screen problem that affected a small(ish) proportion of displays with the first generation mini, it should connect up using the adapter just fine, and be correctly recognized by the system.

  • Does Windows 2008 Server run ok under Mac Mini Bootcamp?

    Does anyone have any experience of installing and running Windows 2008 Server on a Mac Mini (of which has either Mac OS or Mac OS Server installed), under Bootcamp?
    I currently have an old Dell with Windows 2008 server which acts as my Domain Controller, Exchange Server for a small home-office network. It's due an upgrade as the hardware is so old (and noisy!) and like the idea of having a nice compact, quiet Mac Mini, but want to make sure it can carry out the same duties under bootcamp on Win2008?

    Windows 2008 can be installed in Boot Camp.  However I don't believe it is officially supported by Apple so there may or may not be issues with installing the Boot Camp Drivers (or future updates to the Boot Camp drivers.)  Not something I'd be recommending for a "production" environment.  If this is a test/dev system, then probably worth trying, depending on how critical your network uptime is.
    Also, you didn't mention if your Dell came with Windows 2008 preinstalled, but if it did, then likely it has a "branded" version of Windows that won't activate correctly on non-Dell hardware.  (If your Windows disks have "Dell" on them, they won't work with the Mac.)  So you may need to purchase a retail or volume license copy of Windows 2008.
    In general, for a server running as a DC & Exchange, you'd want RAID1 as a minimum so that would be the Mac Mini Server, not the "desktop" Mac Mini.  Unless you have one lying around, you're looking at something around $1500-$2000 to start, depending on whether you can transfer your existing Windows 2008 & Exchange installations.  (Another $500-$2000 depending on what vesions of Windows & Exchange.)  And probably 8GB of RAM since Windows 2008 & Exchange on 4GB is pushing it.  Considering the costs, I suggest you look at the Dell T110 series or the HP Proliant 110 series.  Both lines are very quiet and are supported for Windows 2008 from the factory, including Windows Small Business Server, which includes Exchange.  While not as small as a Mac Mini, they are mini towers and about the size of a typical PC desktop.
    If you really wanted a small footprint, then HP has a "microserver" series.  You'd probably need to call HP to get the build you want as the online ordering is limited for that model.  From Dell, there is the Zino model desktop.  Again, not supported for a "server", but you were going to consider a the non-server version of the Mac Mini, then the Zino has at least a chance of you reusing your existing versions of Windows if they're Dell branded, thus saving your something in the range of $500-$2000 for new software.  (But I would NOT recommend a non-server chassis without RAID1 hard drives, so the Zino is not my choice.  I just offer it as a possibility if you accept the risk of an unsupported installation, as would have been installing Windows 2008 in Boot Camp.)
    So yes, it will work.  But I wouldn't recommend it for a production environment, especailly if you have the "desktop" computer without RAID1.

  • 2 different "switchable" audio output (HDMI and analog) with Mac mini

    Hello,
    I have a 2010 Mac mini that I use as a media center.  Its hooked up to my HDTV in the living room via HDMI.  I also want to hook up external speakers via the 3.5mm analog jack.  These speakers are in the kitchen.
    I would like to get my audio through HDMI when I watch TV and be able to get audio output via 3.5mm jack when I just want to listen to music in my iTunes library.  I like to control my iTunes library with the Remote app on multiple devices.
    Is it possible to switch automaticaly the audio output?
    Right now I use my Airport Express to stream music from my Mac mini to the speakers but I think that the Airport isn't really needed since it lies just by my Mac mini.  I'm pretty sure the mini can do both.
    I've tried to hook the speakers to my Mac mini but first: I hear a "hum" in the speakers (wich I don't hear with the Airport) and second: I can't seem to get the audio out in the speakers.
    I've read many posts about the audio midi settings but I can't figure it out...
    Any help?
    Thanks a lot.

    I hit post too early... here's the rest of it.

    See the SoundFlower app- http://cycling74.com/soundflower-landing-page/
    See AU Lab- http://www.apple.com/itunes/mastered-for-itunes/
    With those apps (or combination thereof)
    You can copy an  audio stream from one output to another.

  • Mac Mini as Music Server kinda

    OK i feel like this is a kinda complicated question that requires someone who knows what they are talking about so i appologize.
    Alright i have an external harddrive 1349(800/400) and usb2 and a airport express and a powerbook. And i am wondering if i could connect the ext. hd to the a mac mini and use file sharing to create an alias of the music folder on the hard drive on the mac mini (this i know will work as i already do it on my powerbook) but i want to go further and use file sharing to create an alias of this same folder on the powerbook. Then theoretically i can play my music from the external hd through a mac mini over an airport express and control it from either the powerbook or mac mini.
    I am not sure if anyone will even understand this or understand my vision but if you can confirm that this will work (like absolutely) then that would be much appreciated. I guess one hitch is that it might be slow and skip even if it worked but im not sure.
    Thanks!!!

    '1349' is firewire in apple terminology.
    Use fire wire over USB 2 if you can, USB needs the processor to intervene in the transfer process taking away system resources, FireWire does not.
    as Jan Jaap Kikkert said sharing music with iTunes is easy.
    iTunes is a streaming music server already (On your network only), all you have to do is select share music and look for shared music and pick a name for the shared volume and the music on the one computer will show up in the iTunes of the other (As a separate ejectable volume {with the name you gave it} in iTunes left pane) , as well as the play lists if you expand it.
    You will be unable to rename or alter the mounted play lists or music this way though. and you have to leave iTunes running to act as a server for the stream and to listen for requests.
    Each computer can listen to different songs at the same time if you want.
    Also will share between windows computers (Running iTunes) and Macs transparently.
    As mentioned the advanced tab will let you set the iTunes Library folder to another drive.
    Does it work, actually I was already doing it before I read your post and is playing now (But through a wired network) and

  • Does the Superdrive work with Mac Mini w/out server?

    I want to buy an external Superdrive for my old Mac Mini but I'm not sure it will work because of the information about it on the Apple website.
    It read, "Compact and convenient, the MacBook Air SuperDrive connects to your MacBook Air computer or Mac mini with Snow Leopard Server."
    What is meant by "a Snow Leopard server"?  I have Snow Leopard on my Mac Mini but it's not connected to a server.  It's a standalone computer in my home. Does that mean it won't be supported by a Mac Mini unless it is on a server?
    Thank you in advance for answers.

    If you're in the market for a new Mac mini, observe that the external SuperDrive is compatible with the newest Mac mini; in fact, it's offered as an option when you order one from Apple's site. The caveats linked to above are about Snow Leopard, which isn't supported on the newest machines — it won't even install without jumping through hoops.
    If you want to save money by buying the older version, do bear in mind that the CPUs on the latest models are significantly faster — for comparison, the 2011 minis, while slightly slower, are in the same ballpark as the 2011 iMacs, wheras the fastest 2010 mini is slightly slower than the slowest "early 2009" iMac.
    The new ones also have a Thunderbolt port.
    If you do decide to go the eBay route and you're concerned about buying a broken Mac, look for one covered under the AppleCare Protection Plan (you can verify coverage by getting the serial number and checking here), as it's transferable and, given that the last model was released less than two years ago, it'll have at least a year of coverage left.
    To be on the safe side, you should ensure the seller transfers the warranty with Apple — while they'll honor it regardless, a shady seller could request a pro-rated refund from Apple on the remaining AppleCare at any time after the sale, since they'll have proof of purchase and it'll still be in their name. Not sure how to do this, because I've never bought a Mac on eBay — the one time I tried several years ago, there seemed to be more scam artists than legitimate sellers (to be fair, I was in the market for a G5 tower when it was the current high-end and retailed for several thousand dollars).
    Finally, factory refurbished 2010 minis with full Apple warranties appear on the Apple store site (at a discount) from time to time.
    In case it isn't obvious, I'm in the market for a new mini myself.

  • [iPhone] Is a Mac Mini good enough for iPhone development?

    Hello,
    I tried to search on this topic, but...not much luck.
    Anyway, I am considering getting a Mini as a reasonably priced entry into iPhone development. But I'm concerned, does the Mini have enough horsepower for the task? I'd rather not be limited in terms of what I want to play with (potentially, both "productivity"-type apps, as well as some gaming development). Will a Mini serve me well, or is this a Bad Idea?
    Thanks!!

    The mac mini is fine, and frankly having a superpowerful machine for development is a mixed blessing because the actual machine is such a dog, that you get careless about speed. But of course your development time is shortened somewhat. THe key to keeping a mac mini happy is to make sure you have enough RAM. 2 GB is needed for all the tools to be running at once. Also you can hot-rod your mac mini with a 7200 RPM drive and really perk it up. Or of course use an external firewire drive.

  • Mac bloqué au démarrage après un changement de permissions

    Bonjour,
    J'ai récemment acquis un nouveau MacBook Pro 15". Totalement nouveau, je débute facilement jusque aujourd'hui.
    J'ai vu dans les "informations" du disque dur "MACINTOSH HD" plusieurs options permettant de limiter les permissions. Pensant alors pouvoir mieux sécuriser mon MAc, j'ai supprimé les permissions pour "Wheel" et "Everyone". Du coup, quand j'allume mon Mac, il reste bloqué sur la Pomme.
    Je ne sais que faire, je n'ai pas encore fait de sauvegarde et j'ai du travail important stocké sur le disque dur.
    J'ai déjà essayé plusieurs fois de réparer les permissions via "Utilitaire de disque" en restant appuyé sur ALT au démarrage, mais rien ne fait
    J'ai aussi essayé en mode Single User, mais je ne comprends pas grand chose et ca me dit principalement que je n'ai pas les droits pour modifier les permissions. Quelqu'un pourrait-il m'expliquer comment pouvoir réinitialiser celles-ci via Single User ou autre moyen ?
    Merci beaucoup.

  • écran mac mini 2015

    bonjour a tous,
    je suis sur le point d'acheter une tv panasonic 55ax630e en 4K.
    pour l'instant mon mac mini est relié a un moniteur qui est une autre tv samsung de 40" en 1080p et tout va bien.
    mes questions sont :
    - la sortie du mac mini limite la 4k en 30Hz. ça va être genant sur la Panasonic ? des petits lag etc ?
    - plus important ... y aura des salades si je met les deux écrans en meme temps ? le mac mini est assez puissant sachant que j'ai le modele de base avec l'intel HD5000 ?
    - si vraiment rien ne marche, je changerais de modele pour reprendre une tv en 1080p. dans ce cas la, plus de problemes ?
    je pense mettre la tv 4k sur le HDMI, et le samsung en 40" 1080p avec un adaptateur thunderbolt HDMI. c'est bon ?
    merci pour vos réponses;
    cordialement

    Pardonnez mon français de Google. Si votre anglais ne est pas bon, vous pouvez trouver le forum à http://forum.macbidouille.com/ préférable d'obtenir une réponse compréhensible.
    1. Vous pouvez trouver les spécifications à http://www.everymac.com/systems/apple/mac_mini/specs/mac-mini-core-i7-3.0-late-2 014-specs.html utile pour déterminer si ce est le adaptateur vous donnant des problèmes avec l'écran, ou si ce est vraiment une limitation du matériel de Mac.
    2. Vérifiez avec le fabricant de l'écran se ils ont de l'expérience connexion au Mac Mini et si il ya certains paramètres qui fonctionnent mieux. Parfois, un cadre entre 1080p et 4K existe qui offre un meilleur support de fréquence.
    3. SwitchResX et DisplayConfigX sont des logiciels qui offrent un meilleur réglage fin de la résolution que ce qui est intégré à Mac:
