Unreal Engine has some specific hardware and software requirements for running the Editor. This page covers these requirements, as well as describing what is installed by the pre-requisites installer included in the Unreal Engine installer.
Company has some Mac boxes which I use to run the builds. Unreal has an option to build remotely with any Mac machine with Xcode installed in your local network or with VPN. In your case you wouldn't need to buy expensive MacBook Pro's just to develop comfortably, simple Mac Book Air would do to run the builds with your PC/Laptop. Aug 05, 2019 Unreal has an option to build remotely with any Mac machine with Xcode installed in your local network or with VPN. In your case you wouldn't need to buy expensive MacBook Pro's just to develop comfortably, simple Mac Book Air would do to run the builds with your PC/Laptop. Copious amounts of RAM is the single biggest contributor to a smooth user experience. While the editor and engine don't use 32 GByte, having the memory available for the disk cache is a boon, especially as a programmer compiling the full engine. We found going above 32 GByte resulting in diminishing returns. Aug 05, 2017 Here's a tutorial on how to download and install the Unreal Engine on a Mac. When we're done, we'll create our very first program called 'Hello World'. Unreal Engine download: https://www.

Minimum requirements for running the engine or editor are listed below.
The requirements for programmers developing with the engine are listed below.
Graphics Card Drivers
We currently recommend using the latest stable releases from each card manufacturer:
Performance Notes
This list represents a typical system used at Epic, providing a reasonable guideline for developing games with Unreal Engine 4:
Windows 10 64-bit
64 GB RAM
256 GB SSD (OS Drive)
2 TB SSD (Data Drive)
NVIDIA GeForce GTX 970
Xoreax Incredibuild (Dev Tools Package)
Six-Core Xeon E5-2643 @ 3.4GHz
If you don't have access Xoreax Incredibuild (Dev Tools Package), we recommend compiling with a machine having 12 to 16 cores; however, we encourage you to read the Hardware Benchmarks (2017) reference to learn more about compiling with and without XGE.
In addition to being added to the generated UE4 project under the Config/UnrealBuildTool folder, UnrealBuildTool reads settings from XML config files in the following locations:
Engine/Saved/UnrealBuildTool/BuildConfiguration.xml
User Folder/AppData/Roaming/Unreal Engine/UnrealBuildTool/BuildConfiguration.xml
My Documents/Unreal Engine/UnrealBuildTool/BuildConfiguration.xml
Keep reading to learn more about the following properties, which help to set and customize build configuration(s).
BuildConfiguration
Whether to generate dSYM files Lists Architectures that you want to build
Enables address sanitizer (ASan)
Enables thread sanitizer (TSan)
Enables undefined behavior sanitizer (UBSan)
Specifies the file to use for logging
When enabled allows DMUCS/Distcc to fallback to local compilation when remote compiling fails. Defaults to true as separation of pre-process and compile stages can introduce non-fatal errors.
When true enable verbose distcc output to aid debugging.
Path to the Distcc and DMUCS executables.
DMUCS coordinator hostname or IP address.
The DMUCS distinguishing property value to request for compile hosts.
Whether to use the no_watchdog_thread option to prevent VS2015 toolchain stalls.
Whether to display the XGE build monitor.
When enabled, XGE will stop compiling targets after a compile error occurs. Recommended, as it saves computing resources for others.
Whether to write a solution option (suo) file for the sln
Whether to add the -FastPDB option to build command lines by default
Whether to generate per-file intellisense data
Whether to include a dependency on ShaderCompileWorker when generating project files for the editor.
Enables the debug C++ runtime (CRT) for debug builds. By default we always use the release runtime, since the debug version isn't particularly useful when debugging Unreal Engine projects, and linking against the debug CRT libraries forces our third party library dependencies to also be compiled using the debug CRT (and often perform more slowly). Often it can be inconvenient to require a separate copy of the debug versions of third party static libraries simply so that you can debug your program's code.
Enable inlining for all modules.
Whether to enable support for live coding
Whether the XGE controller worker and modules should be included in the engine build. These are required for distributed shader compilation using the XGE interception interface.
Whether to unify C++ code into larger files for faster compilation.
Whether to force C++ source files to be combined into larger files for faster compilation.
Use a heuristic to determine which files are currently being iterated on and exclude them from unity blobs, result in faster incremental compile times. The current implementation uses the read-only flag to distinguish the working set, assuming that files will be made writable by the source control system if they are being modified. This is true for Perforce, but not for Git.
Disable optimization for files that are in the adaptive non-unity working set.
Disables force-included PCHs for files that are in the adaptive non-unity working set.
Backing storage for bAdaptiveUnityDisablesProjectPCH.
Creates a dedicated PCH for each source file in the working set, allowing faster iteration on cpp-only changes.
Creates a dedicated PCH for each source file in the working set, allowing faster iteration on cpp-only changes.
The number of source files in a game module before unity build will be activated for that module. This allows small game modules to have faster iterative compile times for single files, at the expense of slower full rebuild times. This setting can be overridden by the bFasterWithoutUnity option in a module's Build.cs file.
Forces shadow variable warnings to be treated as errors on platforms that support it.
Forces the use of undefined identifiers in conditional expressions to be treated as errors.
New Monolithic Graphics drivers have optional 'fast calls' replacing various D3d functions
New Xbox driver supports a 'fast semantics' context type. This switches it on for the immediate and deferred contexts Try disabling this if you see rendering issues and/or crashes inthe Xbox RHI.
An approximate number of bytes of C++ code to target for inclusion in a single unified C++ file.
Whether to stress test the C++ unity build robustness by including all C++ files files in a project from a single unified file.
Whether to globally disable debug info generation; see DebugInfoHeuristics.cs for per-config and per-platform options.
Whether to disable debug info generation for generated files. This improves link times for modules that have a lot of generated glue code.
Whether to disable debug info on PC in development builds (for faster developer iteration, as link times are extremely fast with debug info disabled).
Whether PDB files should be used for Visual C++ builds.
Whether PCH files should be used.
The minimum number of files that must use a pre-compiled header before it will be created and used.
When enabled, a precompiled header is always generated for game modules, even if there are only a few source files in the module. This greatly improves compile times for iterative changes on a few files in the project, at the expense of slower full rebuild times for small game projects. This can be overridden by setting MinFilesUsingPrecompiledHeaderOverride in a module's Build.cs file.
Whether to use incremental linking or not. Incremental linking can yield faster iteration times when making small changes. Currently disabled by default because it tends to behave a bit buggy on some computers (PDB-related compile errors).
Whether to allow the use of link time code generation (LTCG).
Whether to enable Profile Guided Optimization (PGO) instrumentation in this build.
Whether to optimize this build with Profile Guided Optimization (PGO).
Memory for imac intel core duo. Basically, you can add extra memory and swap out your drive.
Whether to allow the use of ASLR (address space layout randomization) if supported. Only applies to shipping builds.
Whether to support edit and continue. Only works on Microsoft compilers.
Whether to omit frame pointers or not. Disabling is useful for e.g. memory profiling on the PC.
If true, then enable memory profiling in the build (defines USE_MALLOC_PROFILER=1 and forces bOmitFramePointers=false).
Enables 'Shared PCHs', a feature which significantly speeds up compile times by attempting to share certain PCH files between modules that UBT detects is including those PCH's header files.
True if Development and Release builds should use the release configuration of PhysX/APEX.
True if Development and Release builds should use the checked configuration of PhysX/APEX. if bUseShippingPhysXLibraries is true this is ignored.
Tells the UBT to check if module currently being built is violating EULA.
Tells the UBT to break build if module currently being built is violating EULA.
Whether to use the :FASTLINK option when building with /DEBUG to create local PDBs on Windows. Fast, but currently seems to have problems finding symbols in the debugger.
Outputs a map file as part of the build.
Whether headers in system paths should be checked for modification when determining outdated actions.
Whether to clean Builds directory on a remote Mac before building.
Whether to write detailed timing info from the compiler and linker.
Whether to parse timing data into a tracing file compatible with chrome://tracing.
Whether to expose all symbols as public by default on POSIX platforms
Which C++ stanard to use for compiling this target
Whether to strip iOS symbols or not (implied by Shipping config)
Whether to ignore import library files that are out of date when building targets. Set this to true to improve iteration time. By default we don't bother relinking targets if only a dependent .lib has changed, as chances are that the import library wasn't actually different unless a dependent header file of this target was also changed, in which case the target would be rebuilt automatically.
Whether debug info should be written to the console.
Whether to log detailed action stats. This forces local execution.
Whether the hybrid executor will be used (a remote executor and local executor)
Whether XGE may be used.
Whether SN-DBS may be used.
Enables support for very fast iterative builds by caching target data. Turning this on causes Unreal Build Tool to emit 'UBT Makefiles' for targets when they're built the first time. Subsequent builds will load these Makefiles and begin outdatedness checking and build invocation very quickly. The caveat is that if source files are added or removed to the project, UBT will need to gather information about those in order for your build to complete successfully. Currently, you must run the project file generator after adding/removing source files to tell UBT to re-gather this information.
Whether DMUCS/Distcc may be used. Distcc requires some setup - so by default disable it so we don't break local or remote building
Whether to allow using parallel executor on Windows.
HybridExecutor
Maximum number of actions to execute locally
BuildMode
Whether to skip checking for files identified by the junk manifest

If true, sets the master project name according to the name of the folder it's in
Whether we should include configurations for 'Test' and 'Shipping' in generated projects (pass '-NoShippingConfigs' to disable this)
LocalExecutor
Processor count multiplier for local execution. Can be below 1 to reserve CPU for other tasks. When using the local executor (not XGE), run a single action on each CPU core. Note that you can set this to a larger value to get slightly faster build times in many cases, but your computer's responsiveness during compiling may be much worse.
Maximum processor count for local execution.
