MACKOS — END USER LICENCE AGREEMENT
Version 1.0
Copyright © 2026 Dan Maxwell. All rights reserved.
IMPORTANT — READ THIS BEFORE USING THE SOFTWARE.
This End User Licence Agreement ("Agreement") is a legal agreement between you
(either an individual or a single entity, "you") and Dan Maxwell ("Licensor")
for the software product identified above, including its executable files,
associated media, and printed or electronic documentation ("Software").
BY INSTALLING, COPYING, RUNNING, OR OTHERWISE USING THE SOFTWARE, YOU AGREE TO
BE BOUND BY THE TERMS OF THIS AGREEMENT. IF YOU DO NOT AGREE, DO NOT INSTALL OR
USE THE SOFTWARE, AND DELETE ALL COPIES OF IT IN YOUR POSSESSION.
1. LICENCE GRANT
Subject to your compliance with this Agreement, Licensor grants you a personal,
non-exclusive, non-transferable, non-sublicensable, revocable licence to install
and use the Software in unmodified form on any number of computers that you own
or control, for your own personal or internal business purposes.
2. RESTRICTIONS
You may not, and may not permit any third party to:
(a) sell, rent, lease, lend, host, or otherwise distribute the Software, or
charge any fee for it, whether alone or bundled with anything else;
(b) modify, adapt, translate, or create derivative works of the Software;
(c) reverse engineer, decompile, or disassemble the Software, or attempt to
derive its source code, except to the precise extent that this restriction
is prohibited by applicable law;
(d) remove, obscure, or alter any copyright, trademark, or other proprietary
notice contained in or displayed by the Software;
(e) use the name "MackOS", or any of Licensor's names or marks, to endorse or
promote any product without prior written permission.
3. OWNERSHIP
The Software is licensed, not sold. Licensor retains all right, title, and
interest in and to the Software, including all intellectual property rights in
it. No rights are granted to you other than those expressly set out in this
Agreement, and all rights not expressly granted are reserved.
4. NO AFFILIATION; THIRD-PARTY TRADEMARKS
The Software is an independent work. It is not affiliated with, authorised by,
endorsed by, sponsored by, or in any way officially connected to Apple Inc. or
Microsoft Corporation.
Apple, Mac, macOS, and Macintosh are trademarks of Apple Inc. Windows is a
trademark of Microsoft Corporation. All other trademarks are the property of
their respective owners. Any such marks are used solely for identification and
descriptive purposes, to state what the Software resembles and what it runs on.
The name "MackOS" is a play on words and is not intended to indicate origin
with, or approval by, any third party.
5. MODIFICATION OF SYSTEM BEHAVIOUR — ACKNOWLEDGEMENT
You acknowledge that the Software alters the appearance and behaviour of the
Windows desktop shell. Among other things it may register application bars,
reserve screen working area, read the list of applications pinned to your
taskbar, enumerate open windows, send keystrokes to the foreground application
at your direction, and — only if you enable that setting — add an entry under
the current user's Run key so that it starts with Windows.
You are solely responsible for maintaining backups of your data and for
determining whether the Software is appropriate for your systems.
6. NO WARRANTY
THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITH ALL FAULTS AND
WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE
LAW, LICENSOR EXPRESSLY DISCLAIMS ALL WARRANTIES, CONDITIONS, REPRESENTATIONS,
AND TERMS, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WITHOUT
LIMITATION ANY IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY,
SATISFACTORY QUALITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, TITLE,
QUIET ENJOYMENT, AND NON-INFRINGEMENT.
LICENSOR DOES NOT WARRANT THAT THE SOFTWARE WILL MEET YOUR REQUIREMENTS, THAT
ITS OPERATION WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE, THAT IT
WILL BE COMPATIBLE WITH ANY PARTICULAR HARDWARE OR SOFTWARE, OR THAT ANY DEFECT
WILL BE CORRECTED. NO ADVICE OR INFORMATION, WHETHER ORAL OR WRITTEN, OBTAINED
FROM LICENSOR CREATES ANY WARRANTY.
THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE SOFTWARE, AND AS TO
THE RESULTS OBTAINED FROM USING IT, RESTS WITH YOU.
7. LIMITATION OF LIABILITY
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL LICENSOR
BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR
CONSEQUENTIAL DAMAGES WHATSOEVER, OR FOR ANY LOSS OF PROFITS, REVENUE, GOODWILL,
USE, DATA, OR OTHER INTANGIBLE LOSSES, OR FOR BUSINESS INTERRUPTION, COST OF
SUBSTITUTE GOODS OR SERVICES, OR COMPUTER FAILURE OR MALFUNCTION, ARISING OUT
OF OR IN ANY WAY RELATED TO THE SOFTWARE OR THIS AGREEMENT, HOWEVER CAUSED AND
UNDER ANY THEORY OF LIABILITY, EVEN IF LICENSOR HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
IN ANY EVENT, LICENSOR'S TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO
THIS AGREEMENT SHALL NOT EXCEED THE AMOUNT YOU ACTUALLY PAID FOR THE SOFTWARE,
OR FIVE UNITED STATES DOLLARS (US$5.00) IF YOU PAID NOTHING.
SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES OR THE
LIMITATION OF LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO SOME OF THE
ABOVE EXCLUSIONS AND LIMITATIONS MAY NOT APPLY TO YOU. NOTHING IN THIS
AGREEMENT LIMITS LIABILITY FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE,
FOR FRAUD, OR FOR ANY OTHER LIABILITY THAT CANNOT LAWFULLY BE LIMITED. IN SUCH
CASES LIABILITY IS LIMITED TO THE SMALLEST EXTENT PERMITTED BY LAW.
8. NO SUPPORT OR UPDATES
Licensor has no obligation to provide maintenance, support, updates, upgrades,
or new releases of the Software. Any that are provided are governed by this
Agreement unless accompanied by different terms.
9. TERMINATION
This Agreement takes effect when you first use the Software and continues until
terminated. It terminates automatically, without notice, if you breach any of
its terms. On termination you must stop using the Software and delete all copies
of it. Sections 3, 4, 6, 7, 10, and 11 survive termination.
10. GOVERNING LAW
This Agreement is governed by the laws of the United States and of the state in
which Licensor is domiciled, without regard to its conflict-of-law provisions.
The United Nations Convention on Contracts for the International Sale of Goods
does not apply. You may have additional rights under the mandatory consumer
protection laws of your own country, which this Agreement does not affect.
11. GENERAL
This Agreement is the entire agreement between you and Licensor concerning the
Software, and supersedes all prior or contemporaneous understandings about it.
If any provision is held unenforceable, it shall be modified to the minimum
extent necessary to make it enforceable, and the remaining provisions stay in
full force. Licensor's failure to enforce any provision is not a waiver of it.
You may not assign this Agreement; Licensor may. The Software is subject to
United States export control laws and may not be exported contrary to them.
