Mar 03, 2012 Gameboy Development on Mac OS X. Building only a simple game for PC or any of the latest Mobile-platforms (iOS, Android) can take month when you also have some sense for art and style. With a four-color 160×144 pixel display, you are so restricted on itself, that doing the graphics yourself is quiet easy; even for someone that is not a. Mar 03, 2012 It contains four command-line tool for which two are the assembler and the linker. Unfortunately, there is no binary available for Mac OS. Fortunately, it is open source. With minor modifications I was able to compile the tools for Mac OS X Lion. You can find the compiled binaries (rgbds.tar 361 298) and the Makefile I used in my github.
MacOS’ Mission Control and full-screen mode are great for swiping quickly between apps and keeping your workspace organised. But what if you want to work in a different way? What if you want multiple windows open on one screen, but in a way that’s neat and tidy and allows you to move from one to the other easily?
That’s where Mosaic, available in Setapp, comes in. Mosaic allows you to tile open windows on your Mac screen so that they are all visible at the same time, but also neat and tidy. This app has a library of set layouts for tiled windows. When you drag a window on your Mac, the layout view appears as an overlay on screen and you choose the one you want, and where you want the current window to sit in that layout. You can then add more windows to the it.
Layouts can be organized in groups – such as those for two apps, three apps, etc. And you can create your own if none of those in the library suit you. And, as a final neat touch, you can control Mosaic on your Mac from an accompanying iOS app.
9 easy steps to split your Mac monitor into two screens (and more)
When you have multiple apps open on Mac, a great way to re-arrange them on your desktop is by using Mosaic. This windows manager lets you fill your Mac screen with apps windows, without having to manually move and resize them. So you can use apps side by side, without the distraction of other windows. Here’s how to use Mosaic to tile open windows on your Mac screen.
Step 1: Get a windows manager app
Search for Mosaic in Setapp and click Install. Once it’s installed, agree to it opening at login, or not if you don’t want it to, and give it permission to manage windows in Accessibility preferences. Click the button on the window that’s displayed on-screen to go to the Accessibility pane, then click the padlock, type in your password and click the box next to Mosaic.
Step 2: Tile the first window
- Choose a window that you want to tile, click and drag it. The Mosaic layout library will appear.
- Drag the window onto a layout and over the position you want it to take, then let go.
- The window will snap into position.
Step 3: Tile the second window
Choose another window you want to appear on the screen alongside the one you just tiled, and drag it onto the same layout in a different position. The two windows will now appear on-screen in the layout you chose. You can click on one to make it active and work on it, just as you would normally.
Step 4: Change side by side layout activation settings
If you don’t like the layout view appearing every time you drag a window, you can change that behaviour so it only appears when you drag a window to the top of the screen or when you hold down the Alt key and drag a window. Click the Mosaic menu bar item, navigate to ‘Show Layouts’ and choose the option you want.
Step 5: Change group settings
By default, only the most common layouts are shown when you drag a window. To change that so that all layouts are shown, or those from a specific group:
- Click on the Mosaic menu bar item.
- Navigate to the Drag & Drop section and hover over Group.
- Choose the group whose layouts you want to see when you drag a window.
Step 6: Change layout view settings
If you want to change the way layouts appear when you activate Layout view, that’s easy too. By default, they appear in a row on the screen and if there are too many for one view, they’ll wrap onto a second row. You can change that to a column view – similar to row view but with layouts displayed vertically; a grid view – that displays layouts on a grid in the centre of the screen; or docked view – that displays half-size layouts docked to the top of the screen. To change the view, click on the Mosaic menu bar item and select Layout View, then your choice of view.
Step 7: Change keyboard shortcuts
To activate Layout view from a keyboard shortcut, rather than by dragging and selecting, make sure the window you want to apply the layout to is selected and press Alt-Shift-Cmd-L. You’ll see the Layout view appear on screen. Click on the layout you want to use. To change the keyboard shortcut, go to Preferences the Behaviour. Click on the keyboard shortcut at the bottom of the window and type a new shortcut. To change how layouts activated by a keyboard shortcut appear on screen, click on the Mosaic menu bar item, go to the Click & Select section and choose a Layout View. To change which layouts are displayed, do the same, but choose a Group instead.
Tip: You can set up Drag & Drop differently from Click & Select so that when you activate Mosaic using one method it displays one group of layouts and when you activate using Click & Select it displays a different group.
Step 8: Set more keyboard shortcuts
You can also set up keyboard shortcuts for positions within layouts. So, for example you could set one up for the left side of a two-window layout where the windows are side by side and each occupy half the screen. To do that, go to Preferences and click the Layouts tab. Choose the Left layout in the list of layouts in at the left of the window, then click Record shortcut. Type the shortcut you want to use. Now repeat for the Right layout, using a different shortcut. To test it, go to a window on screen, click on it and type the shortcut for Left or Right. The window will move into position.
Step 9: Customise new layout
If none of the layouts in the layout library are suitable for your work, you can create a new one. Go to Preferences and click on the Layouts tab. Click the ‘+’ at the bottom of the list of layouts. Select New Layout. Give the layout a name and, if you want, record a keyboard shortcut for it. You can also specify which screen it appears on if you use multiple displays. If you want to use the default 8x8 grid and 32-pixel gutter (the space left between windows so they or their shadows don’t overlap), just draw the layout on the grid by clicking and dragging. If you want to change the number of rectangles in the grid or the size of the gutter, click on the three dots next to the option you want to change and make a selection.
It's not hard to be productive with your Mac when you combine Mosaic, Workspaces, Focus and other productivity apps on Setapp.
Do you have any windows management tips you wish to share?
Put your Mac to sleep
You can save energy by putting your Mac to sleep when you're not using it. When your Mac is sleeping, it's on but consumes less power. And waking your Mac from sleep is quicker than starting it up after it's been shut down.
To put your Mac to sleep immediately, do one of the following:
- Choose Apple () menu > Sleep.
- If you use a Mac notebook computer, close its built-in display.
- Press Command (⌘)–Media Eject (⏏).*
- Tap the power button on your computer.*
*These options don't apply to MacBook Pro models with Touch ID.
Adjust settings in Energy Saver
When you don't use your Mac for a while, macOS can automatically turn off features that you aren't using. When the computer needs to perform a task, related components power back up.
You can adjust energy-related settings in the Energy Saver pane of System Preferences:
- Choose Apple menu > System Preferences.
- Click Energy Saver.
Display sleep
You can tell your Mac how long to wait before it puts its display to sleep. Turning your display off is useful if your computer is performing a task (such as playing music) but you don't need to see anything that the computer is doing.
Putting your display to sleep stops the video signal to any internal and external displays. For Apple displays and built-in displays, this also means that the backlight on the LCD is turned off to save energy.
When your display goes to sleep, the screen goes dark or turns off, but apps that are still busy on your Mac stay active. If your display has a power indicator, it may change to indicate that the display is in low-power mode. To wake your display, move the mouse, touch the trackpad, or press a key on the keyboard.
Put hard disks to sleep when possible
This setting powers down the hard drive motor when you aren't reading or writing files from the drive. Solid-state drives (SSDs) don’t have moving parts, so this setting doesn’t affect Mac computers that use only SSDs to store data.
Consider deselecting this option if you have an internal or external non-SSD drive and you use apps—for example, pro audio or video editing software—that work better with continued read and write access to the hard disk.
Wake for network access
Select this option if you want your computer to automatically wake up when someone accesses its shared resources, such as shared printers or iTunes playlists.
This setting applies to wired connections from other computers, such as Ethernet connections. It also applies to Wi-Fi connections if you use a properly configured AirPort base station. Some tasks might prevent the computer from sleeping when idle.
Enable Power Nap
Power Nap allows your Mac to occasionally wake from sleep to perform tasks such as checking for new email or software updates.
During Power Nap, your Mac leaves its displays and other hardware that isn't needed for these tasks powered down to save energy. After it's finished, your Mac automatically goes back to sleep to save energy.
If you don't want your Mac to wake up on its own to perform these tasks, deselect this option.
More options
You might see more options in Energy Saver preferences depending on whether you use a Mac desktop or notebook.
iMac, Mac Pro, and Mac mini
When you use a desktop Mac, you can control when your computer, display, and hard disks are put to sleep to save energy.
These options are available on iMac and Mac Pro:
Mac mini has these options:
Turn display off
With some Mac desktop computers, you can set how long to wait until the computer enters its lowest idle power mode. This setting is different from display sleep because other parts of the computer also sleep.
If you set the computer to never sleep using this slider, the display and other elements of the computer remain in a fully powered state.
Start up automatically after a power failure
You can set your Mac desktop computer to automatically restart if its AC power connection becomes unavailable. For example, if there's a power outage, or you inadvertently disconnect the AC power cord, your Mac starts up again on its own once power is reconnected.
Mahjong Free Games
You can automatically re-open windows, apps, and documents on your Mac after it restarts, which is useful if you have your computer set to perform tasks when it's left unattended.
MacBook Pro, MacBook Air, and MacBook
With Mac notebooks, some options are available when the computer operates on battery power, and others are available on AC power. For example, you might want your computer to never sleep when you are connected to AC power. But when it’s on battery power, you might want it to sleep when it’s been idle for only a short time so that the battery remains charged longer.
In the Energy Saver preference pane, select the Battery or Power Adapter tab:
Automatic graphics switching
The automatic graphics switching option appears on Mac notebooks that have more than one built-in graphics chip. When you select it, your computer uses its low power graphics chip for tasks like text editing to save energy. For higher-intensity tasks, like playing games or compressing video, macOS automatically switches to another more complex graphics chip.
If you deselect this option, your computer always uses high-performance graphics, which uses more energy.
Other sleep modes
Some Mac computers enter special sleep modes when you leave them idle for a long time, helping them conserve even more energy.
Standby Mode
For Mac computers that start up from an internal SSD, macOS includes a deep sleep mode known as Standby Mode.
Mac computers manufactured in 2013 or later enter standby after being in sleep mode for three hours. Earlier models enter standby after just over an hour of sleep. During standby, the state of your session is saved to flash storage (SSD). Then, the power turns off to some hardware systems such as RAM and USB buses.
Standby extends how long a notebook computer can stay asleep on battery power. A notebook with a fully charged battery can remain in standby for up to thirty days without being plugged in to power.
Safe sleep
macOS also includes a deep sleep mode known as safe sleep. Your Mac might enter safe sleep if your battery begins to run low, or your computer is left idle for a long time.
Safe sleep copies the contents of memory to your startup drive and powers down the computer, allowing you to pick up where you left off without losing your work.
To wake your Mac from safe sleep, press its power button. If you use a Mac notebook and its battery is low, connect the AC adapter first.
When you wake your computer from safe sleep, a progress indicator appears. This indicates that the previously stored contents of memory are being read from the startup disk and copied back into RAM.
Waking your Mac
To wake your Mac from any of these sleep modes, do one of these:
- Tap the computer's power button.
- Click your mouse or trackpad.
- Open the lid on your Mac notebook.
- Press a key on a connected keyboard.
If you use sharing features on your Mac, other computers that use these services may be able to wake your computer on demand.
