Tip: Hurtig og nem konvertering af videofiler på Mac

Skal det være nemt og ligetil, så brug Finders indbygge værktøj til konvertering af videofiler på din Mac.

Normalt plejer vi at anbefale Handbrake til konvertering af video på Mac, men der findes en hurtigere og nemmere metode. I Finder i OS X er der nemlig indbygget videokodning. Alt man skal gøre er at højreklikke (eller ctrl + klikke) på den film, man vil kode. Det bringer en menu frem, hvor man blandt andet kan vælge “Kod valgte videoarkiver”. Man kan snildt markere flere film ad gangen, hvis man har behovet.

I det vindue, der kommer frem, skal man vælge opløsning samt hvilket formål konverteringen har, og et sted til den ny videofil. Herefter er der bare at vente. Det kan godt tage lang tid, så det er smart, at man kan følge med i udviklingen i menubaren øverst ved at klikke på det lille tandhjul.

Er du på OS X El Capitan, skal du ned i bunden af højrekliksmenuen, Tjenester, for at finde muligheden for at konvertere videofiler.

Der er ingen tvivl om, at Handbrake giver større frihed og bedre resultater, men Handbrake er til tider så avanceret, at almindelige ikke-nørder opgiver. Her er Finder-metoden helt perfekt. Den er så enkel at alle burde kunne finde ud af det.

Sådan skifter du RAM på din Mac

Se hvordan du finder ud af, om du kan opgradere mængden af RAM i din Mac. Det er nemlig ikke alle Mac’s hvor det kan lade sig gøre.

Computere kan i princippet ikke få for meget RAM. Jo mere RAM man har i sin Mac desto bedre vil det hele køre. Det gælder selve styresystem OS X samt alle de programmer man bruger. Ofte er det RAM’en og ikke processoren der er den begrænsende faktor for ens Mac’s ydelse. Forstået på den måde, at det oftest er RAM, der er mangel på og ikke rå processorkraft. At opgradere RAM-mægden i sin Mac vil derfor give et voldsomt boost i ydelse. Ofte i en grad, så man kan holde liv i sin gamle Mac et par år endnu. Typisk har den nemlig rigelige med processorkraft til at afvikle OS X fornuftigt, men mangler RAM.

Hvad er derfor mere nærliggende end at putte noget mere RAM i sin Mac? Det er en billig måde at få mere saft og kraft, og forholdsvist nemt at gå til i de fleste tilfælde.

Det største problem er ofte at finde ud af, om ens Mac overhovedet kan opgraderes på RAM-fronten. Det er nemlig ikke alle Mac’s der kan det. På nogle modeller er RAM loddet fast på bundkortet eller utilgængelig på anden vis.

Værst ser det ud for de bærbare Mac’s. Hverken MacBook Air eller MacBook kan RAM-opgraderes, mens der gælder for MacBook Pro, at kun modeller fra midten af 2012 eller tidligere kan opgraderes med mere RAM. Alle nyere MacBook Pro kan ikke opgraderes med mere RAM.

Det samme gælder for Mac mini. Kun 2012-modeller eller tidligere kan opgraderes med mere RAM.

Bedre ser det ud for iMac’ens vedkommende. I hvert fald for den store 27″ iMac. Her kan alle modeller opgraderes med mere RAM. For den lille 21,5″ iMac er det igen kun de ældre computere, hvor RAM’en kan skiftes.

Summasummarum så er det faktisk kun på den store 27″ iMac samt ældre modeller af de andre Mac’s at Apple tilbyder at brugeren selv kan skifte RAM. En vigtig lære her er, at næste gang du skal købe en Mac, så få den konfigureret med som meget RAM som muligt, når du køber den. Bordet fanger nemlig, da man ikke selv kan smide mere i senere.

Den nemmeste måde at finde ud af om ens Mac kan få mere RAM er at trykke på Apple-logoet i øverste hjørne på ens Mac. Her skal man vælge “Om denne Mac” og trykke på fanebladet “Hukommelse”.

Her kan man se hvor mange RAM-pladser ens Mac har, hvor mange af dem der er i brug, og ikke mindst om RAM’en er til at udskifte. Hvis RAM’en kan opgraderes vil der være et link til fremgangsmåde, hvis ikke vil det stå der.

Den praktiske fremgangsmåde til selve udskiftningen er forskellig fra model til model. Det nemmeste er at følge linket, jeg nævnte ovenfor.

Ellers er her links til Apples egne oversiger, hvor fremgangsmåde for de enkelte modeller er gennemgået (på dansk):

How to Take Screenshots of the Login Screen on any Mac

Taking screen shots of the login screen on a Mac is possible, and you can do so at either the OS X system boot, any login window, or at a locked user authentication screen. How a screenshot of the Mac login screen is accomplished will depend on what version of OS X the Mac is running however.

We’ll run through the process of taking a screenshot of a login screen and login window in all versions of Mac OS X. As you’ll see, the process is very easy on modern versions, whereas prior releases of Mac OS are a bit more involved.

Taking a Screenshot of the Login Screen in OS X EL Capitan

The latest versions of OS X 10.10 (and beyond) support the regular screenshot keystroke at all login windows. This makes taking a screenshot of the login screen or a setup window just as easy as taking one anywhere else:

1. Access the login screen of OS X either on boot, through a locked screen saver, or Fast User Switching menu
2. Hit Command+Shift+3 to take a screenshot of the login display

The login window screenshot will appear on the desktop with an “LW” prefix to the regular screenshot file name, like this: “LWScreenShot 2016-12-04 at 12.43.23 PM.png”

For example, if you have customized your login screen wallpaper in OS X El Capitan, you can now easily share that with the world by using the standard screenshot command sequence. Very easy.

Taking Screen shots of the Login Screens in Earlier OS X Versions

Capturing a picture of the login window in earlier versions of OS X is a bit more technical and it involves a multiple part sequence; enabling remote login on the Mac with SSH, then connecting to the Mac with SSH to issue a command. Here are the steps for those interested in achieving this:

1. First, enable SSH on the Mac to allow remote login connections, this needs to be done on the Mac which login display you’d like to screen capture, make note of this machines IP address if you aren’t aware of it
2. Get to the login display on the Mac you just enabled SSH with, either through the screensaver lock screen or the fast user switching login screen
3. From another computer (Mac or anything with an SSH client), login to the prior Mac with ssh by specifying the proper IP:

ssh mac@192.168.0.150

4. Now logged into the target Mac with the login screen active, issue the following command line sequence to capture a screenshot on the target Mac:

screencapture ~/Desktop/login-screen-shot.png

5. Login to the Mac as usual, and locate the newly created ‘login-screen-shot.png’ file on the desktop

You can then disable SSH if you want, or keep it on if you think you’ll want to connect again.

Another option with all versions of OS X is to take a screenshot of login windows through virtual machine software, though that’s obviously going to depend on what app you’re using rather than the Mac OS release.

As you can see, prior versions of OS X require quite a bit more effort to take a picture of the login windows and login screens, and require network access, whereas the latest versions of OS X are as simple as pressing a keyboard shortcut.

How to Add a Location to Pictures in Photos for Mac

The latest versions of Photos app for Mac allow users to add geographic location data to any pictures stored within the image browser. This can be helpful for organizing photos, sharing with others where a picture was taken, and for later recollection purposes too. Additionally, you can edit the location of pictures as well, so if a photo was incorrectly assigned a location, you can change that in the OS X Photos app.

You’ll need Photos for OS X running on at least OS X 10.11 or later to have the location adjustment features.

How to Add a Location to a Picture in Photos for OS X

You can add locations to single pictures or multiple images, depending on what you select in Photos app:

1. Open Photos app and double-click on the photo you wish to add a location to (alternatively, you can select multiple pictures from the Albums or Photos view if you wish to apply the location to all selected images)
2. Click on the (i) button in the Photos menu bar to bring up the image info inspector window



3. Click in “Assign a Location” and start typing the name of the location – this uses a location search based on the Maps application to find* and assign locations, so select a matching location from the search and hit “Return” to assign that location to the picture when satisfied

Once assigned, the location data appears in the Image Information panel on a map, as you can see here with a picture from the Grand Canyon:

*At the moment there does not appear to be a way to assign locations based on maps and dropping pins alone, you must use the location search feature within Photos

Once the image has been assigned a location and saved, if you export the picture the new GPS geolocation data is stored as part of the images EXIF data, meaning you can find the exact location in Preview, another Mac with Photos, or any other image viewer capable of reading location data (which is most nowadays).

This is a nice feature if you want to selectively add locations to pictures yourself rather than having the iPhone assign them though GPS, particularly if you’re one of us who disabled iPhone GPS automatically adding geotagged locations to photos taken with the camera, or if you manually strip out GPS EXIF data of image files, which is sometimes desirable for user privacy purposes.
